installed firefox 3.5 beta 4 the other day. All good so far no probs with add ons. Geolocation bar is looking promising. Private web browsing is cool if the pc is used by a guest.
Just an update - so far, keeping my Flash down an update seems to have sorted the problem - very strange since most people don't have a problem but some people do.
But if it's working I'm not gonna argue the technicalities
