An unexpected error occurred during installation.

Does not work.

the language is still English
i can't note move to french

i m searching for firefox 68 french language pack. Why is that impossible to retrieve old versions ?

Downloaded it and it is NO WERE to be found to use it ...

Added this language to firefox. Shit doesn't work. Restarted browser, restarted PC, pure trash.
I have no idea what the F*** firefox is doing these days but adblock, language packs, so many things are broken. Getting sick of all this broken trash. Amateur developers.

Cette extension ne fonctionne pas pour moi depuis plusieurs versions de Firefox / This extension no longer works for me since a few versions of Firefox.

I couldn't install it and can not use it! so I can not possibly evaluate this... sorry !
