I just started using this new web browser called Flock. It's really similar to Firefox, but has tonnes of little gimmicks. If you're into social media, such as Facebook, Twitter, Digg and Pownce, check it out. I don't know if I would switch from Firefox to this new browser, but it's pretty cool to play with. I haven't figured out most of the features yet, but it's a cool little toy. Anyone else used it? Check it out here.
