I used wmode="transparent" in <object> and <embed> tag for a flash movie in HTML.
While testing the page (using a german keyboard) and filling in form data in the flash movie, I encountered the problem that some characters were wrong. It seems that english keyboard characters appear. Only special characters seemed to be affected like @ or $ or ^.
In IE6 it worked fine.

Reproducible: Always

Steps to Reproduce:
1.open http://www.bannerscreen.com/bannercreator.htm
2.type in some special characters like @ or $ in one of the input fields (happens with german keyboard)

I can confirm this with the Flash 8 and Flash 9 plugin with Firefox 1.5 and a current SeaMonkey trunk build.
jmott: I think this bug here is a possible bug in the Flash plugin.

We have several open bugs on this in the player bugbase.  I went back to look at my old notes, and here's what I wrote about a similar issue with French and Japanese:

[jmott 12/2/04] Adding info about French problems - some characters (like %, | or >) just can't be typed. For example, '%' is supposed to be generated where '"' is on the english keyboard

Netscape - NPP_HandleEvent does not forward WM_IME_*. FOL - Bugzilla bug 272847.

[jmott 12/2/04] Windows IME not displaying is FOL per Microsoft tech support - we went around with this back in 2002.

Investigating french keyboard input not working.
[jmott 12/2/04] French issues are Netscape only!
[jmott 12/2/04] French issues due to NPP_HandleEvent not forwarding WM_CHAR - we fake WM_CHAR in WM_KEYDOWN.
[jmott 12/2/04] This is also FOL, and I've added it to the bugzilla bug. The only way around this is to code up a custom shift table for every language we support, which just doesn't seem worth it.

I have done some tests with a test gmx account and have tested the current GMX Mail Client and a new version called GMX 2007 (beta).

Firefox is fine on both UI's - no problem with the current and Beta UI and german keyboard

Firefox 3 Beta 2 is also also fine and i can write/send mails and using the german keyboard. There is a unrelated issue with Firefox 3 Beta 2 and some special layout features (like bold fonts etc) in the UI beta version and i will send this to GMX.

Trunk works also fine on the current GMX Mailclient UI

I have tried it with the German version of Firefox 3 Beta on a German keyboard. The result is the same as in the privies version. 

In wmode = default 
I am able to typ the @ sign and other high ASCII characters (works as expected)

In the wmode = opaque and wmode = transparent 
I still have the same problems.

I can not typ the special characters which need the shift key or ALT Gr key pressed.

The result is like I wouldn’t press the shift or ALT Gr at all. Otherwise it does recognize the other keys of the German keyboard correct. 

Comment 12

We still have the original problem, which causes this bug and bug 272847.  When the control is running with wmode = opaque or wmode = transparent Firefox stops dispatching WM_CHAR (and WM_IME_*) events which the player depends on.  See the test case provided for 272847 - Neither German ALT Gr input nor IME based input works.

This is NOT fixed - I just checked with the latest FireFox ( - I didn't try v3).  You can try it at our site http://g.ho.st (specifically the service at http://g.ho.st/vc.html) - I am trying a Hebrew keyboard and all characters come out in English (for example ask for a password reminder then you get an edittext where you can type Hebrew chars in IE but not in FF

In reply to comment #10, I'm sorry to say that this bug has not actually been fix in any version of firefox including the current or even the new FF3. I have no idea how you can say that it has? Do you have any idea what we are actually talking about here?

wmode=transparent seems to switch the keyboard to a standard US layout - not UK which is why the @ symbol is only displayed with 'Shift and 2'

It would appear that the programmers of this browser simply don't care how badly or slowly Flash is rendered, and after many years of having this problem
, thousands of complaints posted on the internet and at least half a dozen new releases of FF that still don't have a fix for this bug, it can only mean one of the following:

None of their programmers know how to fix this problem because their too stupid, or none of the programmers care that their browser doesn't work with the world's most important Internet animation tool.

I hope this comment has annoyed someone at Mozilla sufficiently enough to actually do something about this problem that has now been dragging on for years.

Have an email textfield="@" to put the character there in the first place (which looks very tacky)

Don't use wmode at all (Which makes the form look very uninteresting)

Have a message displaying "This website is best viewed in Internet Explorer" (Which I think is a much, much better browser in every way, even though I dislike Microsoft as much as the next man but, IE makes FF look like the slow, buggy, patchy, flakey, rubbish that it is.

The attachment above is a temp. fix for the problem (AS2)
All you need to do is create an inctance of it in your movie (anywhere) and it will take care of the rest.
It will automatically fix most characters (hopefully all) in all textfields.
The change occurs after the user releases a key, which makes for a glich. You can see the actual change happen. But that is something you will have to live with.
The characters are changed into the Swedish keyboard.
Should be pretty straight up to change it to you language!

Do not tell Mozilla this is a fix because it is not ... keep actionscript with actionscript, Mozilla development with Mozilla development.

The class you upload is not a fix but an helper to correct some wrong typed characters in some language only. Their is plenty of keyboard layout all around the world, we cannot use a huge class with all charmap for all languages.

Confirmed on FF3 on Vista Business (FR).

When my Flash movie is set to Opaque or Transparent in the wmode, entry fails, can't detect simultaneous ALT or SHIFT + a key. For an eMail entry form, it's bad.
Also happens in Opera (which uses the same plugin).
IE is spared.

(plugin problem, anyone ?)

Annoying since, as Tek said, a class with all possible keyboard matrixes (plus a logic allowing to select yours) would be awful to program, and I'm not even speaking about the VK "workaround", even more awful.

Comment 33

11 years ago
Here is my attempt at a workaround for this: http://analogcode.com/p/JSTextReader/ . Reroutes input flow via javascript (which is not affected by the browser/flash bug of course), works with most keyboard layouts (more complicated ones like Japanese appear beyond salvation). Works for the FF version of this bug and its IE  ("strange characters") manifestation as well. 

Comment 34

11 years ago
The AS2 class is not a fix as it limits some character inputs and this is not usable on a text field where the user is allowed to enter free text. It might be fine for one country but websites are viewed by people all over the world so trying to map the key codes to a specific country keyboard layout is simply not realistic. 

For the current project I'm working on - 13 languages -, I had to do a JS browser detection to remove the wmode parameter from the swf settings in the embed and objet tags for FF3. 
No one was aware of this bug and it has caused some stress to my client, the people I work with and a waste of time and money for all of us. Not to mention that my client might look somewhere else for his next flash based project. 
Now, the design of the background is simply a solid color for FF3 users. I can't  imagine all the headaches when a javascript menu has to appear on top of the flash content, luckily for my client and me it's not the case here, but I know that it is a common one eg. Adobe's website.

It's not expected from a popular browser to have such HUGE bugs and cause so many troubles to the Flash community of users and developers. I hope that this bug and all the ones affecting the usage of Flash content within Firefox 3 will be assigned ASAP so they can be fixed very quickly and once for all. For the time being I can only tell to everyone I know NOT to install FF3 or to use another browser.

Patrick, if you know someone who is familiar with this issue and would be able to help fix this in the Firefox code please do ask if they could help out here. Any help would be greatly appreciated!

I think this is a Flash Player bug, not a Firefox bug.  I believe that it has the same root cause as https://bugzilla.mozilla.org/show_bug.cgi?id=312920 which has been seen on other browsers that use the Flash plugin -- see comment https://bugzilla.mozilla.org/show_bug.cgi?id=312920#c20 

Comment 37

11 years ago
Please check the earlier comments.  The root issue is that when the player is in windowless mode, we do not recieve WM_CHAR events from Firefox.  We simulate them based on key down events, which is why we loose the keyboard mapping.  Someone needs to change Firefox so that it will send us WM_CHAR events in windowless mode.

Is there any guarantee this will be in the 1.9.1 release? And when would this release be due? your Schedule says mid Nov for beta2, when would the public release go out?
This bug will not be fixed on 1.9.1. Because bug 272847 is not fixed yet. It changes some spec of windowless plugins. So, it should not be fixed after b2.

Help!  Seriously this bug effects millions of users on our site (http://G.ho.st) and many other major sites.  All our users outside the US cannot user their keyboards properly (so the Windows users switch to IE but the Mac and Linux users are completely stuck and cannot user our site).

Is there anything we can do to help get this fixed in 1.9.1?

By the way, why "windowless plugins" - isn't Flash a windowed plug-in?

Alternatively if we could change the spec for windowed plug-ins and have them participate in the z ordering (and why shouldn't they?) then we could have iframes in front of Flash without the need for wmode="transparent" and that would solve the problem for us and many other sites too.


Comment 48

The first post here is 2006 and still this bug has not been fixed. Disgusting!

Seen using Firefox, on Windows XP SP2, Flash version

Using an English keyboard, entering text in a Flash text field, where the Flash file is embedded with wmode=transparent, the @ symbol gives a ". This seems to work OK if the wmode=window (ie not transparent).

So this renders my e-mail entry text box as unuseable on Firefox currently.

Bug 272847 was fixed on trunk. I think that this bug can be fixed by flash player side. But I cannot input ä, ö and ü from German keyboard layout even if I switch the system locale to German. (Of course, I used the test version which given by Jeff.)

I Concur, I've already explained to Nike the issue and have highlighted this thread as a possible fix to the issues we've encountered. I can't wait to let them know you've fixed it, and finally update our designs to no longer use split input fields for email addresses.

Jeff -- I remember Flash supporting unicode as far back as Flash Player 6.  What does Flash need to support to resolve this isse?

Comment 55

11 years ago
This works fine on IE - I don't think it's to do with unicode in Flash

Comment 56

11 years ago
Flash supports Unicode data, it has never supported Unicode keyboard input.  We get our keyboard input from the OS / host app in code page and convert it to Unicode.  This causes all sorts of messy problems.  The next version of the player should support real Unicode keyboard input.

Zvi, the reason it works in IE is that in IE we get WM_CHAR events in windowless mode.  In Firefox we don't - until Masayuki lands his patch.  However, when that patch lands the WM_CHAR events we're going to get will be Unicode events, so we'll have to change the player (which we're already working on for all targets) to deal with Unicode WM_CHAR events.

Comment 57

11 years ago
I hope that as a result of this fix the same thing won't happen as is happening in IE/wmode=transparent - which is that (at least) each of the cyrillic characters entered get broken from a single 4-byte character into 2 2-byte characters, resulting in garbage being displayed.

Comment 58

11 years ago
Note: this bug has been confirmed fix at Laszlo for our use case: entering german '@' sign with wmode='opaque' (which had the same behavior as transparent)

Took a little while to be sure.  We have a feature that is enabled when the user agent contains "Firefox" which had to be hacked to make it work with Minefield that does not contain "Firefox" in the user agent string.  Is that on purpose?
Yes, it is on purpose that Minefield is called Minefield. It means that it is an experimental build.
Web developers shouldn't do UA detection to make scripts work, in general.
using Firefox in an UA detection string is wrong in every case, use Gecko instead : http://www.geckoisgecko.info/

You won't see this bug fixed until you have new releaes of both Firefox and Flash Player.  I don't know which Firefox release the fix will be in, and I can't comment on exactly when the Flash Player will be released.

Comment 63

11 years ago
Jeff, this is pretty unacceptable, there have been plenty of Firefox and Flash Player releases since this problem was first reported in the middle of 2006.  I'm sure I speak for this whole group, and Flash developers everywhere, when I say we deserve SOME kind of estimate as to when this long overdue bug will be fixed.  This is preventing all non-us keyboards from inputting text into Flash for any layered implementation.  This precludes all kinds of commerce, interactivity, and web 2.0 promise, international audiences have been left 5 years behind the curve.

The cynical part of me can somewhat understand that Mozilla might not have that much interest in making the preeminent rich media application work properly under their browser for most of the world, but I'm deeply surprised that Adobe is letting this gross oversight go ignored for so so long.  That you are refusing to put any weight behind an initiative that is so vitally important.  Reading through Adobe documentation, one gets the feeling that you don't even understand the depth of the issue, that you think this is a annoyance regarding a few special characters and not something that renders double-byte input useless.  

This is a formula for self-inflicted obsolescence.

Comment 67

Well, #63 was a little harsh (for all of that FF is a great product and it's
free) but yes, many people have been waiting for this for a long time.

Here's another point - for us and maybe for most sites the main issue requiring
wmode=transparent/opaque is that we want to show iframes in front of the flash
programs.  Now it turns on that for FF on Linux/Mac you can show an iframe in
front of a Flash without using wmode=transparent at all (as you can on IE,
Chrome and Safari).  

So for us even better than fixing this issue would be changing FF on Windows to
behave like FF on Linux and other browsers and allow iframes to be layered in
front of Flash movies.

In the meantime by the way we have implemented a workaround to pass in the keystrokes from Javascript onkeypressed event - that works for European languages but not for the text input programs used with Asian languages.

Hi Zvi,

Yes, we have the same issue, when using the iFrame feature. However, it seems to  happen for ALL browsers here. If wmode=tranparent is not set, (using wmode=window. The iFrame wouldn't be able to display on top of the Flash. Is there other alternative, to workaround the iFrame issue, so that ONLY FF cannot work?

I think we put launch the iframe from another div or something and it displays fine in front of the Flash an in all browsers except FF/Windows and Safari.  As I said it works fine in FF on Linux/Mac which is why I hope they could fix FF/Windows to behave the same

With the actual nightly I have now the problem that the special keys TAB and BACKSPACE no longer work in the flash application.
TAB leads away from the flash application to the browser URL window and BACKSPACE goes back on page in the browser (like you hit the back button).

You can verify that at the above mentioned page:
With former versions that worked fine.

Works with Minefield 3.2a1pre and Flash Player, SWF in opaque mode and Swedish keyboard.

The problem of the key mappings with wmode=transparent
were indeed fixed in Firefox 3.5.6, but the problems are back as of 3.6.3 (verified on 3.6.10 as well).

This was verified with flash player WIN 10,1,82,76
and a Belgian keyboard.

Typing the @ character (= Alt-Gr + 2) in a flash inputfield does NOT work
when wmode is set to transparent.

It seems kinda sloppy that this bug was re-introduced because I'm 100% sure it was gone with Firefox 3.5

Comment 84

Would it be possible to update the status of this bug to "critical" ?

Using something other than wmode=transparent is not an option for my website,
so I currently have found no other option than to add a warning to users of the website, indicating that FireFox contains a bug.

You can test the behaviour at www.energiedesk.com/Offerte.html

Teoli2003, this problem is NOT local to my computer and has been verified

But you appearantly tested this with FireFox 4.0 beta release, while
I clearly indicated that the problem occurs with the current production release.
(Firefox 3.6.10)

Anyway, your post indicates that the next production release (4.0) should fix this bug again, which is what I hoped for.
ZigDaPig, you should try in Fx 4.0beta, then with the latest Flash Player. You're the only reporting this in Fx 3.6 for the moment, so maybe the condition to trigger the bug are more complex than the steps you gave in comment 83.

This bug is triggered for all keyboards where you need to type a combination of 
<Alt-Gr> + <another key> to get a certain symbol.

So it appears to be linked to the Alt-Gr key.

e.g. The same problem occurs with a US keyboard where the €-sign is under
Alt-Gr + 5
Also true for German keyboards. Alt-Gr + E or Alt-Gr + Q doesn't print anything.

This bug is back in FF4. It was gone in FF 3.6

Tested on Win XP and Win 7: A flash object in wmode opaque or transparent will not accept any character that needs the AltGr key. As international keyboards generate the @ sign with AltGr, input of Email addresses in flash objects with transparent/opaque won't work. That makes many websites useless...

Thanks for taking a look.

Agree with last comment. You can test this bug with FF4 on the flash application embed in this page http://nicolas.cynober.fr/blog/116,flex-workaround-for-wmode-bug.html
Josh, is there a new keyboard input spec for windowless plugins or is that Mac only?

It's worse this time. With Versions before 3.6.5 I had the chance to use a workaround for the key mapping. Now even the wrong keys won't find their way into the flash container.

I hope this time we won't have to wait 4 years for a fix of the problem.

To my kknowledge, nothing has changed on the Flash Player side. If there is anything I can do to help get this resolved please let me know.

I just tried debugging the latest player against the latest released version of FF4.  Using a Russian keyboard and the sample app here http://baseonmars.co.uk/bugs/wmode, when I press the 'a' key in the top box (window mode) I get a WM_CHAR event with a uParam of 1092, which the player renders as 'ф'. When I press the 'a' key in the second box (opaque mode) I get a WM_CHAR event with a uParam of 97, which renders as 'a' of course.

Hope that's helpful.

Sigh.  User error.  Keyboard choice didin't follow from one window to the next. Russian works fine in all cases. I do see the issue with AltGr on German keyboard - AltGr+e in windowless produces no input. In window mode, I get a WM_CHAR with uParam=8364 and render €. In opaque or windowless mode, I don't get a WM_CHAR.
Hmm, nsWindow still dispatches the native events by plugin event (not keypress event when AltGr is pressed). However, nsObjectFrame::HandleEvent() doesn't catch the event.
Looks like most event handling code doesn't assume the plugin events as input events. That causes the difference between keypress event handling and plugin event handling. I'll try to write the fix.
Posted patch Patch v1.0 (obsolete) — Splinter Review
The plugin event is handled by chrome always. We should redirect it to (last) focused DOM window in the window.

# the only caller of NS_IsEventTargetedAtFocusedWindow() is PresShell::HandleEvent().

Hmm, this isn't a bug of Window's widget code, this might be regressed by widget removal or something. Maybe, roc is better widget reviewer?

Patch v1.0

I think NS_IS_PLUGIN_EVENT, NS_PLUGIN_EVENT, and nsWindow::DispatchPluginEvent should all be renamed to something like PLUGIN_INPUT_EVENT and DispatchPluginInputEvent. This redirection only makes sense for input events.

Also, we should have a testcase using the test plugin so this doesn't regress again!

Okay, I'll post the renaming patch on another bug. This patch is very simple, so, I think we can get approval for branches easier than the renamed patch.

I tried to think about the tests for this. But I've not found the smart way. Should I add sendPluginInputEvent() to nsIDOMWindowUtils and test only the communication of the event between widget and nsObjectFrame? I have no idea to test the nsWindow for Windows because it looks the native message queue.
How about using nsIDOMWindowUtils::sendNativeKeyEvent to try to send key events to the plugin?
nsWindow::SynthesizeNativeKeyEvent() doesn't use the message queue of Windows. And RemoveMessageAndDispatchPluginEvent() is never called then.

So, I have no idea of the way to kick RemoveMessageAndDispatchPluginEvent() from script.
Maybe extend nsWindow::SynthesizeNativeKeyEvent so that if PluginHasFocus, we call DispatchPluginEvent?
Posted patch Tests v1.0 (obsolete) — Splinter Review
How about this test?

I realize that I forgot to remove the plugin name check in SendNativeEvents(). That was added for risk management for final release. We should remove it for other plugins such as Silverlight.

Just to let you know that a similar issue was in Chrome and Adobe has done a fix in the latest 10.3.181:
"I'm the Flash Player dev at Adobe who works on this. Testing with latest Chrome 10.0.648.205 and latest internal player build for player 10.3, WM_CHAR issues are fixed.  Russian / Greek input works, AltGR works"
i checked and it seems to work now on Chrome but not in Firefox 4.

This bug is Gecko's bug, not Flash Player's. Fx4 doesn't send WM_CHAR message to Flash Player if it's windowless and AltGr is pressed.

My goodness gracious. This is not fixed in 2006??

Patch v1.0 (mq)

We should fix this on branches.

This bug had been reported in 2006. The original reported problem was fixed by bug 272847 (on Fx3.6). But unfortunately, the fix is needed the update of Flash Player too. Therefore, this bug wasn't marked as FIXED at that time. And I forgot to close this bug after Flash Player was updated.

When we shipped Fx4.0, this bug was back but it affects only to AltGr and IME. Probably, widget removal or something is the cause of this. On Fx3.6, we don't need to redirect the plugin input event to focused presShell, however, on Fx4.0 and later, we need to do so.

This patch adds the plugin's input event to the list of "events are needed to be redirected to the focused presShell". And the plugin's input event is only used on Windows and it's only dispatched to windowless Flash Player. Not used for other contents. Therefore, the risk is low but the regression is very serious for some users who use AltGr or IME on Flash Player.

But windowless flash are very important :) With flash in window mode, we cannot change the z-order (so it's a nightmare to add HTML/flash above the flash) and indeeed cannot play with transparency.

Someone knows in which future version of Firefox it will be fixed ?
Firefox 4.1 ? Firefox 5 ?

A previous comment from Benjamin S on the 2011-05-04 was mentionning 6 weeks ? How hard would it be to add the fix in the next FF update ?

Comment 124

Yes, I'm a bit disappointed that it is not included at least in firefox 5. 

You may think this bug is not critical but some sites are now broken, like for instance "store.nike.com", where it is not possible de go to the payment step without the ability to enter '@' character which is necessary for emails. 

Of course as a developer I can overcome the bug for my sites by removing wmode transparent, but as a visitor, I see a lot of flash based sites that may or may not be fixed, and are broken right now.

Maybe release-drivers should reevaluate based on above information.

I agree with Nicolas Lann and others.

Many sites including commercial sites can suffer from this, especially in europe where Firefox's market share is high (see here, among other references http://uk.reuters.com/article/2011/01/04/us-internet-europe-idUKTRE70324F20110104) so that's almost 2 on 5 customers that may just think the site is broken and go elsewhere.

A Swiss bank has their users unable to log or even register on one of their websites because of this bug. Go and tell their users that you have to copy and paste your email because the @ cannot be entered under Firefox, so embarrassing. Yes please review your release plan for this fix.

Does this mean that the bug will be sure fixed in firefox 5 ?
Or there is still some process needed to have the fix accepted in this version ?
I tried both Aurora and Beta channels and the bug was still there on both.

I checked again today and it seems to be fixed in the latest Aurora release. 
I see it made the migration from m-c to 6 Aurora but I don't see this in 5 Beta.
