Flock, the Web 2.0 Browser?

Beta 1 version of Firefox-based browser Flock finally released with many polished features.

Some of the features include drag-and-drop photo uploading for Flickr and Photobucket, an in-built RSS aggregator, direct blogging tool, and shared favorites/bookmarks. In step with Web 2.0 philosophy, Flock provides a rich user-centric experience, making it easier to bring information to the user and vice versa. It is available for Linux/Mac/Windows, and you can download it here. (And for those of you trying to get Flash working in Firefox on an AMD64 Linux machine, try this and be pleasantly surprised!)"
