Do you get a crash or a hang/freeze/not responding ?
Your comment doesn't match the summary of this bug.

>that no QuickTime plugin is installed for type OGG

That looks like a error message from a installed quicktime plugin and not from Firefox. Do you see any quicktime parts in about:plugins (enter as URL in Firefox) and which version ?

when firefox stops responding, debug>break in windbg and issue:
!analyze -v -hang

Sorry for not getting back to the machine with the problem.
Able to replicate again once, but not again:
After double-clicking on the "play" button for "Sample ACARS VHF transmission" [URL from script?, not disclosed] the message "You do not appear to have the XiphQT component for QuickTime. QuickTime cannot play Ogg files without this component. Please download XiphQT or choose another player." appears in the small window; then ~15 seconds later Firefox goes to "waiting" cursor, then after a few more seconds, goes gray and Windows reports Not Responding; ie, freeze not crash.

A similar URL, http://en.wikipedia.org/wiki/File:Acars_sample.ogg (and other media pages in the past which require QuickTime), causes a popup from QuickTime to appear at the ~15second point after the "You do not appear to have...XiphQT..." message, but the popup closes and no freeze occurs.

Firefox Tools Add-Ons Plugin shows QuickTime 7.6 installed, even though no permission for it was ever given.

No debugging program is installed (nor permission available).  The Windows "report errors" window closes without displaying any info due to antivirus violation, and log can not be found.

find a computer where you can install windbg, then copy the files to something and then copy them to your target. windbg doesn't need to be 'installed', it just doesn't come in a package other than its installer.

If you can still reproduce using v3.6, please supply stacktrace for the hang.
for now, this is incomplete
