Reproducible: Always Steps to Reproduce: 1.Open ff 2.Go to any tab 3.Open another one(tab) :S Actual Results: It hangs, slows down, the task manager shows 100% CPU utilization, then I close a tab, the CPU becomes 65% (many times), then close ff itself, it goes down then to 2%. Expected Results: Run as before 1 week ago, before installing SP3, this weird behavier actually happened after installing.
Moustafa, does it also happen when starting Firefox in Safe Mode? You should probably also create a fresh profile to run a test. See following URL for the explanation: http://support.mozilla.com/en-US/kb/Profiles Marcia, are there any machines in your lab with SP3 installed?
Version: unspecified → 2.0 Branch
I can verify that has happened to me too. After SP3 i noticed Firefox has been peaking one of my Intel Core 2 Duo, cores and fan has been blowing like crazy. Disabled addons, still no effect.
I don't know why, but since I disabled my bluetooth, the problem is no longer. Normal CPU ratings...
Faisal, does the problem re-occur when you enable bluetooth again? Does that happen when just viewing a page?
Sorry Henrik. Didn't get to ammend my comment. After 2 mins, the CPU clock went up again. So the Bluetooth was NOT a factor... SP3 + Firefox3 = CPU100%. Well, I'm running a Core2Duo, maybe different for diff chips?
Faisal, is it still an ongoing problem with the latest official release of Firefox 3? Sorry for the late reply.
