511811 - High PF Usage when opening Yahoo Mail in Firefox 3.5.X

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[Rai]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2

I've noticed that PF Usage sometimes sky rockets, memory usage goes above 1,4 Gb and this is happening only after I upgraded to FireFox 3.5.x onward (I've been using FireFox since 0.7 version).

At first I thought this was random until I realized it was happening only when I used FireFox and more specifically when I was checking my Yahoo Mail account. Same thing happened when I upgraded FireFox on a notebook and opened Yahoo Mail.
Thing is it does not happen every time so I'm not sure which part of Yahoo Mail + FireFox triggers the high PF Usage but if I use FireFox and no matter how many tabs I open with various sites opened as long as I don't open Yahoo Mail it works just fine.

When it happens it totally slows down my machine and I normally have to 'kill' FireFox from Task Manager by 'End Process' otherwise it does not go away.

Any idea how to fix this problem?

I would really like to stick with FireFox but this problem is really very annoying.

Thanks and keep up the Great work!

Reproducible: Sometimes

Steps to Reproduce:
1.Open FireFox
2.Check Yahoo Mail account
3.Check emails one by one
Actual Results:  
Sometimes PF Usage become very high above 1 Gb and slows down the computer and the only way to terminate FireFox is by ending the process in Task Manager.

Expected Results:  
This never happened before I upgraded to FireFox 3.5.x.

I'm using FireFox 3.5.2 with standard theme.
My machine specs are:
Intel Pentium D 2.8 Ghz
1 Gb RAM
80 Gb HDD
WinXP Pro SP3
