"Firefox + Tab Mix Plus = Internet Explorer 7"
Multiple tab customizations.
Annoying blank tabs when you download files? No option to view tabs as thumbnails? I find it rather amusing (not surprising at all, though) how these cons never come up (and, thus, never count) when CNET is reviewing Firefox. You can either download and install Firefox and Tab Mix Plus and use them together (having in mind every add-on makes your browser startup time slower) or just use Internet Explorer 7, which doesn't have any "blank tabs when you download files" and has an option to view tabs as thumbnails in the first place.
