Firefox 3 Slowness

Ever since i think Beta 1 FF3 has been noticeably slower for me in terms of graphical rendering.
Firefox 2 runs just fine too...

I've tried various versions of it, made new profiles, and all seem to have the same problem.
Now using FF3b5-Systemcairo
For example

this page https://addons.mozilla.org/en-US/firefox/search?q=color
(ironic as this page is the firefox add-ons, which should be coded nicely for firefox, but of all sites i've loaded in FF3 this is definitely the WORST)

runs remarkably slowly in ff3 but runs fine in ff2 (by slow I mean that scrolling the page is very jerky and causes huge CPU spikes, in fact even just focusing the firefox window with that page open causes a big cpu spike)

I've noticed slowness in other areas as well, especially if I install any sort of graphically intense theme (Nasa night launch for example, https://addons.mozilla.org/en-US/firefox/addon/4908 , A very nice theme btw!), causing overall slowness, most noticeable when switching between tabs.

Also notice some delay switching to a tab with a large image loaded in it (usually a screenshot).

Anyone else experienced this??
Why on earth would FF3 be so much slower than FF2 when it's supposed to be faster!

Help is much appreciated!

Re: Firefox 3 Slowness

I'm not so sure this will really help you, but I find Firefox 3 waaaaaaaay faster than Firefox 2. This might suggest that there is something wrong on your side, specifically.

I guess that's what Ambi is talking about.

Re: Firefox 3 Slowness

Yeah, I've been using the Firefox 3 package from Unstable, and it's way faster than Firefox 2 for me - I use it as my default browser now.

yea i just tried some of those fixes, but I don't think that is the problem I'm having, the problem reported there has to do with high disk I/O activity.

I'm not seeing any excess disk I/O here, only high CPU spikes viewing certain pages.

Thanks for the suggestions though

but seriously, is this site painful to scroll through for anyone else?
https://addons.mozilla.org/en-US/firefox/search?q=color

it scrolls fine in FF2

*Edit* Tried moving entire ~/.mozilla folder, didn't help

Re: Firefox 3 Slowness

I'm running FFb5 and those sites scrolled ok for me.  I was having that issue running Bon Echo (FF2) but it stopped when I went to the FF betas, beginning with beta 3.

That page scrolls fine here on FFb5. I use to have scrolling issues also on some pages. I followed these steps (and I posted in the other thread):

I deleted the .mozilla directory and set up the browser the way I wanted it. That included disabling the anti-phishing stuff and setting the browsers cache to 1 MB. FF has been running awesome since then.
