Firefox update

I just installed Firefox, the Spanish version, which went flawlessly. It placed the files and updated my extensions. But after one hour I saw a new icon on my screen:

firefox update

Apparently there are updates available, only one hour after I installed it. Almost surely this is an external extension that has quickly been updated after the new release of Firefox, but it will confuse new users.
