Its time to build a browser from scratch... rather than modifying the old versions. MS must come with a new one without changing the brandname like they did with Windows XP. But again they didnt changed the codes of OS when it was released..
I am sure Firefox will continue to enjoy a good share of market for a long time. However, IE is also improving in terms of looks and features.
People are still using IE because its there and its convenient. No need for the hassle of installing another browser. I know because I used to think IE was the greatest gift on this planet...until I started using FF 2.0 and got hooked
I use all of them, starting to use opera more and more tho, tired of FF. What no one using Flock 2.0!!!! lol kidding
