Reporter, firstly, be sure to update to Firefox 2.0.0.3 since it has some security/stability fixes which might be important. :)

Secondly, what kind of system are you running on? Is it able to handle other sites alright or is this a more global issue? Can you try with the latest trunk nightly and see if you experience the same slow down (might want to use a new profile since trunk is unstable)?

It's the same with 2.0.0.3 (with a new profile)

Using Windows' Firefox on the same machine, I never came across problems like this with sites. In Linux, sites that are javascript-hungry such as digg.com are causing problems (I reported them as bugs).

The nightly made a difference actually. Using the nightly (see below for info), the site became usable, however it is still slow to scroll up and down (which means I wouldn't go to that site using Firefox, but it's not a DoS site anymore with the nightly)... 

nightly info (with new profile):

I confirm that problem. I also had similar problem on digg.com. Researched this little bit and it boiled down to be problem with rendering background images. When I disabled http://css.smugmug.com/img/themes/FreshAir/background.gif with Adblock Plus, everything start run smoothly. On digg.com, it was http://digg.com/img/main-back.gif which caused problem. 

Is this bug in background image rendering?

Nevermind, I found PR that better describe my problem.

https://bugzilla.mozilla.org/show_bug.cgi?id=328319

It seems to be problem with stacked transparent backgrounds in Firefox on Linux
and FreeBSD, and have nothing to do with image dimension.
