No browser is 100% perfect! I left IE because of the almost weekly disclosure of securety holes and the time taken to patch it and you can't radically change the functionallity or look of IE. I've even left OE for the same reasons. After looking around the net for a week I decided on Firefox. There were a few reasons why. - vastly more secure than IE with security patches available within days instead of weeks. - Extentions to change the functionality of Firefox. - Tabbed browsing. - Themes to change the look of Firefox. - Built in Ad, spyware and Active X blockers. - A great email client in Thunderbird. - Users, who unlike MS, care about their browser by making their own improvements and sharing them with other Firefox users. Now no matter which browser you pick there will always be hackers out there trying to find holes in it, they live for the challange. You go with the browser that is right for you and for now Firefox is right for me
