I've about had it with IE, two hijacks in the last 30 days. Before I switch to FireFox I've got a couple of questions. Any know compatibility issues with Norton Internet Security 2005? Any known compatibility issues with OutLook Express? I may go to Thunderbird later. Will I be able to switch back and forth (at least initially) between FireFox and IE? I'm running XP, HE +SP2 I did a search and browsed the net for answers to these particular questions, but didn't come up with any. Thanks guys!!
