User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; de; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729)

I have been experiencing problems with videos on firefox on different websites including youtube and the site I linked. The video and audio goes all choppy and my CPU goes to 100%. This has been happening since this morning when my firefox automatically updated. In the beginning it was just some minor errors but it's gotten worse to the point that I can't watch any on firefox. Sometimes the video is still for over 1 minute while the audio is still on. I have tried the sites with different browsers. I don't get this problems with any different browser with any video or site at all.

Reproducible: Always

Steps to Reproduce:
1.Go onto a site with videos such as youtube or http://www.narutowire.com/Bleach-Episode-236/watch/0f43e7595cd4750f3a51/
2.click any video
Actual Results:  
My video and audio got all choppy and my CPU went to 100%.

Expected Results:  
It should have played the video normal and without the CPU suddenly peaking to 100%

I have found out that I have this problem too with some other browsers but only when I activate the full-screen mode. With firefox I have the problem constantly.

include the used plugin version (about:plugins) if you report an issue about a plugin.
Do you alrerady tried http://support.mozilla.com/en-US/kb/Safe+Mode
What do you mean with some other browsers, IE (with a complete differen plugin) or Chrome/Opera/safari (they use the same NPAPI plugin) ?

I think that at least part of it is actually my computer having the problems. by now all my browsers (Opera, IE and google chrome) are experiencing the problems just not as bad as Firefox. With firefox I can't watch any videos but with the others it is just when I activate full-screen mode. But if I activate safe mode, firefox can play videos but not in full-screen mode, just like the other browsers. I have the following add-ons :
-AdBlock Plus
-AOL Radio Toolbar
-BugMeNot
-Downloadhelper(but that's deactivated all the time)
-FireTorrent
-FlashGot
-FoxTab
-gladder
-googlepedia
-PDF-Download
-Read it Later
-SkipScreen
-TinEye Reverse Image Search

I also have the following video plugins:
-DivX Web Player 1.5.0.52
-Quick-Time Plug-in 7.6.2.0/7.6.4.0(both versions of them are listed)
-Shockwave Flash 10.0.32.18
-VLC Multimedia Plug-in 0.9.8.1
-(Silverlight Plug-in 3.0.40818.0)is that a video plug-in?

I got this when I opened "Extras"-Add-Ons. when I typed about:plugins it told me just about the same but a lot more difficult to understand (there were about 6 entries just for Quick-Time Player 7.6.4).

If you right click on the video you should get a hint about the used plugin.
In this case the page is using flash10 and you have Shockwave Flash 10.0.32.18 which is the latest one.

To find the addon that is causing this you can now disable the addons one by one (disable 50% of it, restart ff and test) to find the addon that is causing this.

about:plugins list every single plugin file and quicktime is a collection of different plugins for different file types.

All Browsers except IE5+ are using NPAPI Plugins and if you get the same issue with the complete different IE Active X Flash Plugin you really seem to have a system issue.
You can rule out some broken Flash settings if you test under a different Windows User Login. If you get the same issue there you have really an issue with your system like the graphic card driver or something else.
