477058 - Firefox+X11+Flash plugin: keyboard focus lost when double-clicking in flash

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[James N]

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.6) Gecko/2009020423 Gentoo Firefox/3.0.6
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.6) Gecko/2009020423 Gentoo Firefox/3.0.6

See the URL above for the bug report for the same issue as posted on the Adobe BTS.

I have been asking around for people to test this for me, and it seems to occur for:

*) Linux and Solaris, but not Windows or Mac OS X (which makes sense if it's something related to GTK+)
*) Firefox 3, but not Seamonkey or non-Mozilla browsers (Opera).  Firefox 2 remains untested since it seems to crash when I try even loading the browser.
*) Flash Plugin, but not DJVuLibre plugin (the only other plugin I could test with, since my computer is 64-bit)

It's been confirmed with 64-bit and 32-bit and 32-bit in nspluginwrapper, on Gentoo and Ubuntu and Debian and Slackware and Solaris.

Since it ONLY seems to happen with Flash but, given the exact same libflashplayer.so, ONLY seems to happen with Firefox (not Seamonkey or Opera), I decided it was reasonable to open a bug here for it.

Reproducible: Always

Steps to Reproduce:
1. In firefox on linux, visit any page that contains a Flash animation or game of any kind.
2. Put your insertion cursor in the address bar, so you can see it.
3. Click anywhere inside the Flash animation or game, so that it has focus.
4. Double-click anywhere inside the Flash animation or game.  It has now lost focus, and your insertion cursor should be back inside the address bar.
Actual Results:  
While both clicks seem to go to the Flash animation or game (I haven't been able to test that particularly well), it has now lost keyboard focus, and your insertion cursor should be back inside the address bar.

Expected Results:  
keyboard focus should remain in the Flash animation or game.

I do not know how to debug an issue like this, but considering how easy it is to reproduce, I leave that up to you guys.

I can confirm this on Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2a1pre) Gecko/20090205 Minefield/3.2a1pre ID:20090205022618 ..

For me it happens also when I click once.

I confirm this:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.5) Gecko/2008123017 Firefox/3.0.5
Flash 10.0.15.3
Nvidia driver 180.27
Kernel 2.6.28.3

Are you sure that it doesn't happen with SeaMonkey ?
(you have to use a Seamonkey2 alpha if you compare with FF3 )

[Elez J. Shenhar]

Good observation, Matthias!
As far as SeaMonkey, the problem occurs only with SeaMonkey2 alpha. It does NOT occur with SeaMonkey 1.1.14.

[James N]

Yes, in my original report I was testing with SeaMonkey 1.1.14, where the problem does not occur.  Thanks for testing with SeaMonkey 2, I haven't had the opportunity to do that.

I can confirm this too:
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1.3)
Gecko/20090913
Shiretoko/3.5.3
Flash Player 10 - 10_0_32_18
2.6.30-ARCH

I'm surprised at how old this bug is and even more surprised that there haven't been any workarounds yet. (as far as I know at least)

Allow flash no keys until flash itself modified that adobe flash control features page allows individual users to specify which keys SHALL NOT be used by flash object.  This rather than trying to use the browser, in which flash is a 'guest', to make flash objects behave.

Without the 'user consent in adobe flash setting panel' no keys work.  Flash object in page prompts user to make this setting or flash object (game) receives no use of keys.

It is obscene that I have to use the new tab toolbar button in firefox rather than hotkeys.

Hey all,
 I can confirm all of the above and with firefox shiretoko 3,5.8pre.
Falsh works "nearly" flawlessly on chromium as well.
watching videos on hulu.com  I cannot get any of the flash buttons to work unless I continually click...and even then it doesn work,
 single click on anything flash is the proper performance... and ONLY firefox is not handling this well... I even tried a beta flash ...still the same results.
  This is  a firefox issue and extremely irritating at that!

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
