When playing a movie embedded in a web page (for example, anything from ifilm.com) using Firefox, if you close the window or tab with the movie before it has finished playing, all Firefox windows will freeze. If you let the movies finish, this issue does not come up. The movies I have tested the most are Quicktime .mov files. There is no abnormal output to console, except: "(Gecko:31558): Gtk-CRITICAL **: file gtkwidget.c: line 5663 (gtk_widget_set_events): assertion `!GTK_WIDGET_REALIZED (widget)' failed" which occurs when mplayerplug-in is loaded, and occurs even if Firefox does not end up freezing. I've tried this on various versions of Firefox from 0.9 to present (1.0_rc2), and Firefox binary 1.0_rc1. I've tried many versions of MplayerPlug-in (current being 2.6.6), but found no version which otherwise worked but did not display this bug (some did not play videos at all, all that did play videos seemed to suffer from this bug). I'm using Mplayer 1.0_pre5-r4 currently, but the bug has been present in earlier versions (I'm not sure exactly to which version, though). I have been affected by this bug for perhaps a month or two, although I am not certain what changed (ie, what software I installed) to cause this bug. I'll do more tests after I submit this report... obviously, if I froze Firefox my report-in-progress would be lost. I plan to test: file formats besides .mov, and manually stopping a video before it reaches the end of the clip (and then closing the window/tab). Reproducible: Always Steps to Reproduce: 1. Emerge mozilla-firefox, mplayer, and mplayerplug-in (versions and use flags below) 2. Open two firefox windows or tabs, one with a page containing an embedded movie (window A) and one without an embedded movie (window B). 3. Close window A (the one with the movie) while the movie is still playing Actual Results: Window A closes normally, but window B (and all other firefox windows) will become unresponsive and their displayes not updated (artifacts from overlapping windows stay). Expected Results: Window A should close, and window B (and all other windows) should remain responsive.

this is a bug in firefox/mplayerplugin.. your are probably better to report it to the mplayerplugin authors (or bugzilla.mozilla.org)
I have the same issue with mp3-files.
