Internet Explorer 8 has some stupid bug that makes the scrollbar jump if something in a textbox is too long and you try to edit the middle/end of it.
Opera isn't bad, but it lacks any good add-ons.
Safari is self-explanatory, its internet explorer for the mac.
Chrome has a stupid bug that turns every font in every page into one font, but I do appreciate their mediocre sense of humor.
Firefox is the one I recommend, it has Adblock and Noscript.. making it somewhat the most secure browser... well in my opinion.
