Adblock is a great extension! Even though I use the others more, I'd still have to say it's my favorite.
I also like:
- Statusbar clock (so i can ditch the one in the taskbar)
- Allow rightclick
- and the simple little "go home". (Anything to make my browser a little cleaner is great to me!)
I like the BBCode, but am still getting use to it. I still find myself typing the code out.
I still can't belive more people aren't using Firefox! I've been back and forth between the fox and IE due to little nags, but now I think they've got it ironed out enough for me to totally convert. It's just so useful to have the browser work FOR you and not the otherway around. IE's security issues aside, it's better on so many levels. And it's still beta, I can only think that v1.0 will be even more awesome
Regarding the BBCode extension.... 90% of the time you just highlight the text and right click then select bold, color, italics, etc. With a url, you ctrl-c the actual url then highlight the word then select url - make selection (? not at home right now). Works great.
