Looking like a twat answering myself, but maybe saving anyone else fucking about. Re: Firefox 3 beta..
Seems some are, a lot aren't.
Also, it looks like it's a separate install - didn't bother looking into it - separate directory, but seems to share addons and cookies (prob other stuff too) with ff 2.0 and won't run both together. I bet it's easy-ish to separate them, but I should do some fuckin work...
Are 2.0 plugins generally compatible?
