Sort of late, but there are a few things I wanted to comment on...

1) You say the problem only happens while FF is loading pages, but after that it settles down?
2) Broni asked about the processor type, but you never specified it. Can you specify the type and speed of your processor?

Depending on the machine (and CPU speed), FF may open slowly and eat CPU cycles. This is normal as FF is opening, and also normal when loading a page... especially websites which are flash intensive like Myspace and Youtube. On my X31 Thinkpad, 1.6ghz, 2gig ram, CPU peaks at 72% opening Myspace pages and settles down once the page is loaded. Of course this is also due to Intel speedstep switching from 600mhz to 1.6ghz. If I run my X31 at 600mhz, FF CPU cycles will peak at 87% when loading. If I run the X31 at 1.6ghz, it will peak at 67%. So you can see CPU speed does make a difference. On my desktop, 3ghz, CPU peaks at 15% then settles after the page is loaded.

The reason I'm mentioning this is because I really don't think anything is wrong with how FF is working on your machine. It's just the nature of FF. I wouldn't imagine a machine with a 60gb harddrive and 512megs of ram is running a Core2duo processor... so all of this might just be normal for your machine specs.

Firefox, even version 3, still has memory leaks. Not as much as prior versions though. Crashes in FF can be caused by many things, especially after browsing for a long period of time. I do experience occasional (rare) crashes myself with FF, but it's so hard to pinpoint, I just ignore it and relaunch FF.

Guys, wait. We're talking about two different things here.
We know, that FF has memory leaks, which are getting even worse by accumulating add-ons, themes, etc.
But leaks are about RAM usage.
My Firefox starts with about 70MB of RAM being used. Then, it starts to grow. When its usage grows to 350-400MB, after few hours of usage, it comes to pretty much standstill, and I'm forced to restart it.
However CPU usage is always minimal.
This is my Task Manager after about 3 hours of FF usage:

Broni, I am addressing each subject separately.

The OP stated that he only sees high CPU while FF is loading the page (post 29). Every screenshot the OP posted, he captured while FF was loading the page. From my understanding, the screenshots weren't of the constant FF CPU usage.

My FF usage is also at 0% once the page has loaded, but higher when pages are being loaded. Broni, is your CPU usage "always" at 0%? If so, you have a very fast machine! :)

As for the memory leakage subject, I think it's resolved by all that it's the nature of FF to have to be restarted after long usage.

Yeah, you may be right. I guess, I didn't pay enough attention.
Surely, when page is loading my CPU usage, depending on site, will go up to 20, 30, even 50 %, but it goes back to near 0, right away.
I wasn't even thinking, it may be any big deal.

You need to specify your current specs before any determination can be made. CPU type and speed is important. Admittantly, judging from the info you already specified (60gb, 512megs ram), I have to guess the machine is not the latest... so $300 may not buy you much. However, depending on your machine specs, $300 could mean a processor and ram upgrade (the most important ones!), but don't expect miracles! We'll have to see, so please list the following, and we can go from there...

Make of computer: ie, Dell, HP, home-built
Motherboard: (go to Start>run...type in winmsd... on the System Summary page see if you can find the motherboard/system make/model)
Processor type and speed: (right click on MyComputer, choose Properties, and read what it says on the General tab)
