It seems to me that my Firefox 3.5.2 works a little bit slower than its previous versions. Maybe this will be fixed in 3.6.
BTW, can you please send me your email address that I can use to contact you? Thanks.

I’m not facing any performance issues with fF 3.5.2. May be it depends on the machine or I may not be noticing it. Anyhow, FF 3.6 will definitely have some performance boost.
