Latest Firefox nightly adds tab bar-cramping customization
You can now cram everything into your tab toolbar. Right-click and choose customize, and you're now able to drag-and-drop navigation buttons, the address bar and search bar, or any of the other Firefox menu elements alongside your tabs.
If you're a netbook user and only have a few tabs open at a time, this could be a good way to save vertical pixels on your cramped display. Otherwise, I'm not sure too many people are going to go for this kind of interface cramping. Even on my LG's 1680x1050 screen, more than 5 tabs already starts to feel like a tight squeeze.
More customization options are always welcome, though, and that's a big part of what makes Firefox such a great browser.
