Does it work better in the firefox safemode ?
-> Help/Restart with addons disabled.

Comment 2

Yes, it is still reproduceable in safe mode.

I can't reproduce this bug on the latest Nightly, Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:19.0) Gecko/19.0 Firefox/19.0, Build ID: 20121023030553

I also tried the nightly version with addons disabled, but it's reproduceable...

Oh, there's one notable thing, is that I am involved in the youtube html5 test (while the page is still flash in fact).

[Manuela Muntean [Away]]

Even if you are involved in the YouTube HTML5 test, some videos still load using Flash, so that shouldn't be a problem.

 It's been a while since anyone looked at the issue and I'm not able to replicate it in Firefox 25 or Nightly. I'm going to close the bug. If you see it happen again, please re-open the bug and comment with more information. Perhaps it's been fixed along the way or was a duplicate bug.
