User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30)
Build Identifier:

When using the program Mozilla Firefox, it basically sucks my processor and RAM dry. I've also come to realize that I'm not the only one with the problem. I honestly love firefox which is why I'm wiriting this. I have a a 2.20 GHz processor and 512MB of RAM, so I know it's not because I'm low on those. The only other program I run with it is MSN Windows Live Messenger.

Reproducible: Always

Steps to Reproduce:
1.Restart Firefox
Actual Results:  
Starts over and begins with not so many resources being used, to have my RAM and processor maxed.

Eh, your user-agent string indicates you're running IE7 and not Firefox. I suspect some firefox extension or special firefox build is at play here, maybe you could provide some more information?

Yes. I started using IE7 again because firefox wants to be troublesome. But no, the only thing I have special on firefox is a skin, and that was just added recently, but firefox has ALWAYS maxed my stuff out. I dont use add-ons for firefox because of the issue at hand.
try some of the following steps to narrow down the source of your mentioned problems :

This bug lacks sufficient information to do anything with it, so => incomplete.
Also does not meet criteria for critical.  please read

If you have a reproducible testcase or URL that causes problems, with steps to reproduce, then please post the information and reopen the bug. But frankly I don't see a firefox problem, you simply won't get good performance with XP on 512MB memory - in fact you are _guaranteed_ to have poor performance.  IMO the best you can do is work on optimizing your XP environment and going through the list at

Also, FF3 will use less memory in many situations, so give it a a try when it becomes available.
