I sort of like Firefox but I havn't really made it my home browser yet. I like the RSS subscription tool. Easy. I also like the promise of open source software. I'm not worried I will end up locked into the software with no escape route, which brings me to my next point.
Firefox lacks the dot mac bookmark sync feature of Safari and I can't figure out how to get my bookmarks out of Safari and into Firefox. If anyone is reading AND they know how to get bookmarks transferred or any other cool features I am missing out on, comment now or forever hold your mouse.
