329776 - Windows Media Player causes FireFox to stop responding

Status: RESOLVED DUPLICATE of bug 327639

(Firefox :: General, defect)

Description

[David Mueller]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20060307 Firefox/1.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8) Gecko/20060307 Firefox/1.5

After navigating to certain websites which feature Windows Media content inside their website via the Windows Media Plugin (If I understand this correctly) FireFox will stop responding once the content has been closed.

Reproducible: Always

Steps to Reproduce:
1. Open two tabs (ctrl+t once)
2. Navigate to the URL mentioning in my URL entry.
3. Once the media has finished playing (or has begun) close the tab window [x] leaving only the blank one open.


Actual Results:  
Windows Media Player alerts the end-user that it has (or has been asked) to perform an illegal operation and thus, must shut down.  This problem causes FireFox to cease responding in the current active browser window and leaves FireFox.exe running in the backround until it is forcibly "turned off" by task-manager.

Expected Results:  
The plugin *should* cease to operate and FireFox should dismiss it as such.  It should then leave me with one tab window open.

I have tried to reproduce this on a number of websites - without actually knowing how this is caused (in the technical sense) I am really unable to reproduce it on many websites.  The only one which consistently causes the error is this website and this error is NOT present on 1.5_RELEASE so I am assuming this is an issue either with something that has changed to latest-1.8/latest-trunk.

If I can find any additional websites this occurs with I will try to post them inside this bug report as I grab them.  This occurs with both Windows Media Player 10 and 9.0 as well as whatever version of Windows Media Player is currently being used in Windows Vista.

Steve England kindly pointed out that I should show off the version of Windows Media Player.  Attached is a screenshot that shows that off.  There are no plugins present in Windows Media Player 9.0 nor Windows Media Player 10.0 as both installations are totally "vanilla."

On trunk, I crash (TB16686826Q), while on branch, the browser becomes unusable. Trying to find a regression range now.
