Laurence Simon points to this great article on why Mozilla is better than sliced bread, especially for bloggers. Mozilla’s tabbed user interface is one of the best features of any browser, and it supports a lot of features that IE does not. (Such as proper PNG alpha transparency and popup ad blocking)
So, those of you still using IE should make the switch to Mozilla. It’s free, it’s fast, and it makes web developers happy. (And the sooner that more people use Mozilla, the faster I can implement the spiffy new site design I’ve been mucking with…)
