I've used Fennec, microb, Opera and Chrome under Easy Debian. Fennec was really slow. microb, as other posters have noticed, is good, but mine inserted what looked like settings into the typed URL history, and later on completely deleted all typed URL history, without me doing anything. Also, it's difficult to use with gmail. Opera has a neat interface (I use Opera 11, because Opera 12 crashes randomly for me too, pity) and I use it as a default browser until microb's WYSIWYG-ness is needed (but still don't trust it 100% after the typed URL history debacle).
