210580 - [AxPlugin] ActiveX plugin overriding Mozilla native plugin

Status: RESOLVED EXPIRED

(Core Graveyard :: Embedding: ActiveX Wrapper, defect)

Description

[Rick Alther]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3.1) Gecko/20030425
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3.1) Gecko/20030425

I have Flash 5 installed on IE.  I installed Flash 6.0 r79 on Moz 1.3.1.  I went
to http://macromedia.com and the flash simply does not come up.  I can right
click in the flash area and bring up the popup menu, and it says "About Flash
5".  Obviously, it's picking up the ActiveX version instead of the Mozilla
version of the plugin.

Once I renamed the "npmozax.dll" to a non-Netscape plugin name, the native
Mozilla Flash plugin was properly found.

If I install the latest Flash plugin for IE, then the Flash works except for the
links or Javascript interaction.

I did some searching, and bug 170349 looks like it might cover this, but I'm not
sure.

Also, see bug 203171, as I attributed these problems to something else.


Reproducible: Always

Steps to Reproduce:
1. Start up IE and install the IE Flash plugin (preferably a different version
than the Mozilla one: e.g. 5 or 6.0 r47).  Close IE.
2. Install the Mozilla Flash plugin.
3. Install the Mozilla ActiveX plugin.
4. Visit some Flash websites (e.g. http://macromedia.com, http://scubapro.com)
5. If you installed a different version of Flash for IE, the simply right click
on the Flash and click the About menu item.  You will notice the version # for
the IE plugin is displayed.
6. If they are the same version, then the Flash will visibly work, but non-of
the links in the Flash work if you click on them.
7. Rename the "npmozax.dll" to "_npmozax.dll" and restart Mozilla.  Retry the
above steps and notice everything works fine.

Actual Results:  
The ActiveX plugin is being used in preference to the native Mozilla plugin.

Expected Results:  
I expect Mozilla to check to see if any Native plugins can handle the specific
MIME type first before checking the ActiveX plugin.  There should be some sort
of order or priority for these plugins, and not just for ActiveX.  If two or
more plugins claim they handle the same MIME type, there should be some ordering
(preferably user defined if possible..or maybe it's install order), to determine
which plugin handles it.

Is there the difference of flash plugin is installed [mozilla/plugin] dir from
other dir? 

Comment 2

[Rick Alther]

This also happens on Moz 1.4rc3 as well as 1.3.1

Anyilove, I'm not sure what you are asking.
* The Mozilla Flash and ActiveX plugins are installed in the /plugins directory.
* The IE Flash ActiveX control is installed wherever it gets installed.

The problem is that when the Moz ActiveX plugin is installed, it seems to take
precedence over native Moz plugins and runs the ActiveX Flash control rather
than the Moz Flash plugin.

How was the Active-X plugin installed? Be sure you have the Active-X security
policy because that regulates the ussage of the Netscape plugin.

Comment 4

[Rick Alther]

The ActiveX plugin was installed from here:
http://www.iol.ie/~locka/mozilla/plugin.htm#download

I was unaware of the activex.js preferences file.  Even so, I have no idea what
I would need to put in there to prevent the ActiveX version of Flash from
running.  I certainly don't know the ClassID of the Flash ActiveX control.

Comment 5

[Rick Alther]

I've attempted to find out the Class IDs of the ActiveX Flash object and this is
what I've put into the activex.js file so far with no luck.  The Flash ActiveX
control is still loading:

pref("capability.policy.default.ClassID.CID1171A62F-05D2-11D1-83FC-00A0C9089C5A",
"NoAccess");
pref("capability.policy.default.ClassID.CIDD27CDB70-AE6D-11cf-96B8-444553540000",
"NoAccess");
pref("capability.policy.default.ClassID.CIDD27CDB6E-AE6D-11cf-96B8-444553540000",
"NoAccess");
pref("capability.policy.default.ClassID.CIDD27CDB6B-AE6D-11CF-96B8-444553540000",
"NoAccess");

Comment 7

[Aaron Kaluszka]

Would it be possible to have an option to always load the EMBED instead of the
OBJECT if a plugin exists for it?

Comment 8

[Aaron Kaluszka]

Oh, I guess they are semi-interchangable.  What I mean to say is: can we always
attempt to load a native plugin first and only use the ActiveX plugin if a
native handler is not found.

Comment 9

[Adam Lock]

EMBED tags inside OBJECT tags should be favoured. If that isn't happening, it
sounds like a problem with the plugin API rather than the ActiveX plugin which
is only doing what it's told.

Comment 10

I'm having exactly the same problem. I installed the Mozilla ActiveX control and
now flash doesn't work properly, i.e. I cannot click in flash objects etc.

To prove that Mozilla ActiveX control _is_ the culprit:

I then moved npmozax.dll out of C:\Program Files\Mozilla FireFox\plugins . And
now everything is OK. So the mozilla activex control is interfering with flash!!!
