I have been using the beta versions of Firefox (currently 9.3) and I have no complaints whatsoever, on the other hand I have heard quite a few complaints of Firefox 1.0 being incompatible with many of the extensions that we have come to love. Is there a good reason to upgrade to V1.0? Is it any more stable than the beta versions? Does it offer more or more reliable functionality? I ask because I like the Firefox that I have and I don't want to get rid of it for something that has problems or won't improve on my current version. Is there a good reason to upgrade?
