I like the quicktags that are available in Firefox. They make using a Mac to update this WordPress powered blog very nice.
Normally I still surf with Safari and have been happy with the 1.3 update. It seems faster and the main reason I use it is the decent support for several online financial sites I use as well as being able to synch, through .Mac, with my other Macs. I wish we would get an update that would allow use of formatting tools in blog windows for Safari though.
