what about sessions, speed dial and mouse gestures?

 

There's on-going debate about tabs, but afaik opera came first with being able to do more with them than just have them fixed at the top (eg: tile, resize, etc)

I use Firefox mainly. I love it because of it's programming apps. I also use Opera, it's fast dial makes it great to run runescape and parts of tipit. I have put the fairy rings on a dial as well as the skills I'm up grading.

 

What I wont use is Internet Explorer!!! M$ had the browser market covered and would not fix the problems in IE. They had to brought kicking and screaming into the 21 century to upgrade and comply with web standards. They're not there yet. But, I don't care - I wont use them.
