Always have, ever since I switched from Netscape years back. History does everything bookmarks do, and a whole ****load more. Should try it sometime, I imagine it'd take a while to get used to but once that's over with it's far better.
And, I mean, even if you don't rely on it to the extent that I do, it's still a ****ing pain in the ass when you do need it. Want to find that one page in a hundred you went to looking for that circuit board map/serial number/German porn/whatever? Good luck with the page-based sorting- it's not in alphabetic order, it's not in (the absolutely worthless) time order, it's just plopped down wherever the hell Firefox feels like putting it! WHEE!
