Just finished upgrading all my machines to Firefox 1.o and Thunderbird 0.9. The long awaited release of Firefox 1.0 was well worth the wait. Previous releases had not been the easiest to ugrade to and on one occassion I lost my profile and had to start from scratch. But the upgrade to v 1.0 went like a dream. Not only was it fast and efficient it checked all my plugins, extensions and themes for compatabiity and checked for upgrades.
