Unfortunately it uses too much of the resources - when my Mozilla browser is using 450 MB RAM and I'm using 920 MB of my 1 GM RAM, my machine slows down horribly. Changing windows or tabs leads to applications - or sometimes the window manager - hanging for 10, 20 seconds or sometimes even more.
Swiftfox just crashed. Mhen I restarted and all the same pages were loaded, it was using 170 MB, instead of the 480 MB it was using before the crash. (I hadn't restarted off the browser for maybe a week - I prefer to suspend my machine rather than restarting things, especially when I'm traveling and have poor connectivity.)
