Searchbar Autosizer 2.0.13 doesn't work at all in FF16.0.1 on XP Home SP3.
According to the message I get while opening the settings of the Searchbar Autosizer within the add-on list of FF, there must be something wrong with the prefs.xul in the chrome folder of the add-on.
The message says: "Not defined entity in line 5, column 1".
As for now, I downgraded to 2.0.11, which is perfectly ok (well, as long as you don't mind the settings being english and localized at the same time).
More stars to come after the fix will be available.

EDIT:
I'm on a german system.
Maybe I could fix this myself if you tell me what string is to be translated.

Esta valoración es de una versión anterior del complemento (2.0.13). 

That's an odd problem. It means that an string is not in the translation. Are you running firefox in en-US or a different locale?
