I definitely prefer Firefox. However I do have quite a few browsers installed on my computer, such as Internet Explorer, Opera, netscape navigator and Safari, because sometimes my firewall blocks them for no reason and I looked for other browsers until I worked out what the problem was, and sometimes they randomly don't work anyway. At the moment my Firefox keeps crashing, my Internet Explorer 7 is freezing on starting up more than usual, and Netscape Navigator doesn't always launch either. Good thing I've got Opera and Safari left, lol.
