Firefox Installed: Now what

Okay: I guess a Sunday night is as good a time as any for this Diary.  Figure I won't be pushing too much off the page.

Last week when that new scare over virus imbedded in images occur, it was enough to get me off my ass (so to speak, I didn't actually have to leave my chair) and install Firefox.

I have been using it at home for week or so now, and getting used to it.  I like the tabs and the bookmark folder but am ready to really see what this can do - so tell me my ever so trusty (and when it comes to browsers, opinionated) kossacks, what other cool things should I be doing with this.  What extensions are a must have?  Any website with essential tools that I should check out?  Please take a minute and point the way.

And for those who have thought about making the switch, but were not sure, I must say that installation was a breeze.  It even copies your favorites, homepage, etc.
