Memory usage isn't a concern; all of my boxes have at least 16G if not more. What made me move away from FF (especially on OSX/x86) is being able to sit there and watch it redraw its own window decorations/"chrome". Adding a few extensions/plugins just made it slower. I've got it installed (and updated) on all of my machines "just in case" I run into a site that's broken with Chrome or Safari, but I still have no desire to switch back to it for full-time use.
