Firefox. (Or Bon Echo 2.0a3 to be precise, Firefox 2.0b1 was just to messed up.)
Cannot live without flashblock (or
adblock plus since flashblock doesn't work with 2.0, yet), my
search engines** and
find-as-you-type (AcidSearch cannot be used with Webkit nightly builds, which is the only version of Safari/Webkit based browser that doesn't crash regularly on one of my most frequented sites).
Sage is also a better RSS reader, IMO, than Safari's built in function.
Webkit nightly, that I've been trying out for a while is very nice though, and blazing fast. With a bit better plug-ins control (
flashblock), search engines and find-as-you-type, I might go back to Safari... maybe...
