  1. Actually, I’m running this in a “portable” setting, and so far, so good. No issues whatsoever, and my add-ons work perfectly, despite most of them not being technically compatible with this version. I notice somewhat of an increase in speed with each upcoming version, and this one is no exception. So far, Firefox 9 is very quick and for me, it’s very stable. It can only get better from here.
