What browser are you using?

Chromium. It's like Iron, but without some random untrusted 3rd party packaging it up for you into a neat little .exe (that you'd be foolish to trust any more than, say, Google's Chrome itself).
 


opera for browsing (love them mouse gestures)
firefox for some work stuff
midori, chromium, conkeror for testing + keyword tools

ha ha just a browser whore really
 
Chromium, Firefox, Opera

Opera can be worth another look for people that haven't tried it in a while. It now does good or wins on a lot of the benchmark tests done by various sites. See here, for example.
 
FF 3.6.6 but I also switch over to Chromium a lot.

and lol @ those using chrome.
 
Downloaded Opera 10.6 a couple of weeks ago. I really like it and I'll probably switch over full time pretty soon. Really the only thing that keeps me attached to Firefox is my extensions at the moment. I even like Safari 5 better than Firefox now.

My general feeling is that Firefox gets worse with every new release. I really don't have any evidence to back that up, it's just how it feels to me when I use it now. Once I get comfortable with everything in the other browsers I'll probably ditch Firefox for Opera.
 
Opera, Opera and Opera! Ultra fast and can't live without it! Although I still have Firefox, IE, and chrome installed - just in case if a site doesn't support Opera or perhaps coz of add-ons. But nothing can match Opera IMO and those who haven't, should definetly give it a try; you'll be addicted.
