Following the report from the bug report ##2561, I must clarify the following.

After try one more time to install the @iceweasel-l10n-es-ar@ package, package one more time, I got one more time the error reported on the bug report ##2561. Also, I've installed the @iceweasel-l10n-es-es@ and @iceweasel-l10n-es-mx@ package and both packages didn't change the language of Iceweasel interface. Meanwhile, in Icedove and GNU IceCat, the language packs are working flawlessly fine.


[OFF-TOPIC]

Also, the "about" window is smaller than previous version (69.0), which causes that Iceweasel name looks bigger than the rest of the interface.

Thanks.
