I love Firefox. I was sort of sceptical about tabbed browsing being that much of an advantage, but now I use it all the time. I have two computers - a Win2000 laptop and an OS9 iMac, and Firefox is so good that I rarely use the Mac any more (Firefox doesn't come in an OS9 version); returning to the net with a clunky browser, no tabs, crappy find, pop-ups and new windows all over the place - it's just no fun. Every now and then I come across a page with a plugin that Ff can't find, which is the only disadvatage I've encountered - otherwise, I can't recommend it highly enough.
