OK I Installed v1.2 into it's own folder seperate from v1.0. Everything went well. All bookmarks & other settings have been carried over to v1.2. Is it ok to remove v1.0 now or should I leave it? I don't want to mess any settings up in v1.2. Also what is v1.2b? I downloaded some themes to use with v1.2 that were for v1.2b but when I tried to apply the theme it said it was for an earlier version of mozilla.
