Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

[Michael Rabinovsky]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0a1) Gecko/20120120 Firefox/12.0a1
Build ID: 20120120031125

Steps to reproduce:

*Have two or more windows opened, at least two of them with one or more plugin container contents (like youtube, netflix, a flash game, or flash ad)
*Minimize one of the windows


Actual results:

Firefox hangs and plugin container crashes, without offering a report, restarting it fixes it until next minimize.


Expected results:

The window should have minimized instantly without any hitch

At first I thought those crashes were random and happened just when you minimized the window, then I noticed that they happen every time I minimize a window with something that is clearly using plug-in container (minimize a youtube window while having netflix running in another, etc.)

This doesn't only happen in the nightly versions, I know for a fact it has been happening since Firefox 6 and in the stable versions as well.

Type about:crashes and provide the related crash IDs (bp-...).
Does it happen in Safe Mode (see http://support.mozilla.org/kb/Safe%20Mode)?
Does it happen with a new profile (see http://support.mozilla.org/kb/Managing-profiles)?
