I have tried Mozilla and its variants on several occasions, each time hoping that it will work better then the last time. I really like the tabbed browsing capabilities more then anything. Well I can't seem to use Mozilla for more then a couple of hours before it crashes on me so I thought I was stuck with IE. Then I found
MyIE2. Tabbed browsing, pop up blocker, Google toolbar works, is highly configurable and supports skins. I've been using it for a couple of weeks now and haven't had a crash yet. If you're looking for an IE replacement or want to do tabbed browsing, I recommend giving it a look.
