What would you add to firefox?
I'd add two things, focus on the currently loaded tab, even if other tabs were loading in the background, I hate it if you're typing while other tabs are loading in the background, when they finish loading the focus is sent to them, so you start typing somewhere you can't even see!
The other, Sound only in the current tab. I don't want some tab I'm not looking at to be talking/playing music etc... just mute them! You get two or three sites with sound and its horrible! The ability to mute a tab would be great too.
