Well, not actually a world of difference, maybe just a smal village :) 

I did what is stated above, and installed firefox 1.5, and I notice
small improvement. The number of tabs before I hit 100% processor load
has increased from two-three tabs to like ten. But still, on Windows,
and firefox 1.5 I can have as much as 40 tabs open withouth ANY
processor load. Ff just eats a lot of RAM, and that's it.

I also tried ff on debian testing, same thing. I guess FF just performs
better on Windows machines.
