Description

[Schuessi]

User-Agent:       Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0

Getting "high" cpu-load for firefox.exe if i view a page with animated gifs (smiley-icons). The problem only occurs if Yahoo-Messenger (10 final) is running. As soon as YM is closed cpu of firefox.exe drops, even if it still views the gif's.

Was tested in Safemode and with YM 11beta...always the same problem. Also the Yahoo-Plugin witch comes with the messenger was removed, result was the same.

Reproducible: Always

Steps to Reproduce:
1.start firefox
2.start Yahoo messenger
3. view a page with animated gifs
Actual Results:  
CPU of firefox.exe climbs to about 20%

Expected Results:  
not eating my CPU

Did some more Testing. Have the same issue with Firefox 4.0.1.

The same Test on Windows XP did not lead to high CPU usage.

Works for me on Mozilla/5.0 (Windows NT 6.1; rv:6.0a1) Gecko/20110510 Firefox/6.0a1

Could you see if the issue occurs if using an empty testing profile? (Don't install any addons into it)
