Firefox

I've been using firefox for a while now. I used to switch back and forth, because I couldn't decide which one I wanted to use more, but then IE crashed on my computer and I couldn't open it at all. That kinda sealed the deal.

EDIT: this is a somewhat amusing video:

Firefox for sure. That damn cat is in the way though. LOL

I use firefox in linux, as well as konqueror.
I bet I'm the only one here who has used the latter...

I switched to Firefox the summer of 2006.

Well I am using IE at the moment because Vista is garbage and FF will constantly crash. But I've been using Firefox for a few years, and when I get around to putting a different OS on my laptop I'll use it again.

Firefox... and Opera when I'm on the Wii.

I use opera

I only use Opera, occasionally firefox. Dang I didn't only loose my old account, I lost my status of VGChartz regular! Can't edit games in the database anymore Aaargh!

I use Iceweasel.

@epsilon72: I didn't like Konqueror or indeed KDE3 at all. I use GNOME. I'll have to see how a KDE4 Kubuntu turns out before deciding whether to use that.
