Description

7 years ago
User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.7; rv:6.0.2) Gecko/20100101 Firefox/6.0.2
Build ID: 20110902133214

Steps to reproduce:

Running Mac OS X 10.7.1 x64

Opened 9+ tabs in a single window along with multiple tabs in a few minimized window. 
I then tried to load a flash based page... (youtube, gizmodo, etc.) 


Actual results:

Firefox ran slower than a paralyzed snail! I tried to quit the application and wait 3 minutes for it to close!!

Details- 80-100% cpu usage on a single core (1 of 4) when FF would hit slowdown. My Mac's performance was not affected. 




Expected results:

Firefox should have performed like 6.0 and 6.0.1, because I did many tabs + flash (one version back) without problems. 

I need the firefox version archive to fully validate this, but this is a heads up to not rollout changes so fast!

There have been no problems with Flash + FF 7-18. However smooth playback is seriously affected by the latest flash + FF 19 across OS X 10.7 and 10.8. The playing is not smooth at all, and the video frames will only change when I click the mouse, the audio is not affected, only the video.
Was that introduced with a recent Flash version or the switch to Fx19?
If it was introduced in Firefox, could you try to find when this problem was first occuring using the regression finder?
