Hmmm, Firefox has finally started addressing one of my big gripes, how slow it is when hitting the Back (or Forward) buttons. Opera’s long held the lead regarding that, and is a big reason I won’t consider switching full-time.

Beware, though, it’s very early and experimental, in fact it’s disabled in the nightlies by default. Interestingly they OK’d this to be checked into the trunk code whilst it is frozen except for ‘approved modifications’, as they work towards 1.1. Plus the current nightlies won’t load themes or extensions, so don’t know that I’ll be checking it out anytime soon.
