Eventually they condescendingly acceded to that... in version 24 I think? Soit dit en passant, every modern desktop has got a standard mechanism for reporting download progress... does Firefox use it? No, it doesn't. Apparently it's something to do with "maintaining a consistent look across platforms", i.e., sticking out like a sore thumb in all of them.

Google "Firefox Services", or just read the release notes for recent versions.
Or you may also try this: find one of those little Twitter "buttons" on any webpage (El Reg has them) and right click on it. Look for the additional context menu options.
