Just that. What do you think of Mozilla's latest and greatest... I must say that I like it, as I'm currently using it...
(And Opera is, at my system, faster and kinder on ressuorces, which does matter at my old computer :-P)
I installed it the other day and yesterday got all the addons I need... and its still slow, not as much as ff2, but slow nevertheless.
I have to get an addon for a button to reopen closed tabs, other for a speed-dial, other addon for mouse gestures, etc. All those features are built-in in Opera and its damn fast. Maybe ff3 is faster without any addons but its not such a great browser without them, and when you install all the ones you need and you have 6-7 tabs open it eats up resources and doesnt deliver any speed in return. I hope they continue improving it, but Im sticking with Opera for now.
