I like Firefox personally. I tried using chrome, but unlike Firefox, it doesn't sem as customizable and it seems a little bland. I really son't like Internet explorer because it has WAAY tto many toolbars and it has become to bothersome to use.
Firefox here. I stay for the awesome addons( NoScript, Greasemonkey, Greasefire, Xmarks, Firebug, Adblock, etc.) and the amount of options it gives you is great. I find those two things a great trade off for speed.
Google chrome(chromium on linux) is amazingly fast. Great for quick searches.
Actually it is chrome now on linux and chromium has now been branded as Google's OS which is basically ran off a server instead of being installed.Chrome has those extensions now too....Especially with Chrome Instant from the Dev/Canary build.I used to be firefox before my old computer got hacked :/ Chrome just feels so much nicer and it actually has all the good firefox extensions now and they really improved the extension code for easier(and more functions) for GC.
Ahh...didn't know that about Firebug because I don't use that extension a lot.Chrome can do those things with like 1 extension so it doesn't matter much.Also Chrome gets a better integration and formatting for google products like wave,gmail,maps and etc.Plus we got IE tab!(which is really helpful for those websites designed around IE)
