After firefox has been running for a while (6 - 8 hours) with multiple tabs (4 or more) it consumes memory and CPU cycles.

Curently 30 - 47% CPU usage (That is crazy) I can forward tsk mgr snap shots
Mem Usage 267,348K

PLEASE FIX THIS....

I have XP Pro with all updates applied



Reproducible: Always

Steps to Reproduce:
1.Open firefox use normally
2.Open other tabs and other firefox windows with multiple tabs, use normally
3.Leave firefox alone with firefox windows and tabs open for a few hours (6 - 8 hours)
4.Check Windows Task Manager and get sick because of all the CPU cycles and Memory Usage being leaked by Firefox.
5.Stop using all other programs because Firefox is behaving worse than McAfee
6.Finally reboot your computer out of frustration.
Actual Results:  
CPU Cycles increase consistently
Mem Usage increases consistently

Computer slows to a crawl

Expected Results:  
Expected Firefox to NOT consume CPU & MEM

Sorry but this bug is too general to be useful and such a bug would be also not be fixed in Firefox2.X because Firefox gets only Security fixes at this time.

Please try it again with Firefox3b5 and be sure that you also test it in the safemode (without extensions).
BTW: Why do you reboot, just closing and reopenign Firefox should help.
