thx for the feedback on ffx 3b5. Will play when I get time.
Most important addons for me are Adblock Plus and Greasemonkey. Within GM, most of the scripts i have active are ones that I've hacked anyway (eg one to remove the ginormous headers from BBC website, that adblock doesn't get rid of). So as long as GM works, I can re-hack the GM scripts if need be.
