Global language pack installation

[jumba]

Is there a way to install language packs globally on linux? Can I put them to some global extensions directory? They should only be for PM and not Firefox.

I saw these on the linux FAQ:

Extensions

Pale Moon reads the standard Firefox directories for global extensions, thus extensions may be globally installed. Extensions may be extracted into
/usr/share/mozilla/extensions/
or, for a specific user, in
~/.mozilla/extensions

Are there Pale Moon equivalents for these locations?

I would try /opt/palemoon/browser/extensions (if you installed in the standard location). But this is just guessing based on where Firefox stores the language files.

That worked, while the others didn't. Thanks Sven!
