Forum Bashkësie Firefox

I have both German and Dutch dictionaries downloaded, but firefox' spelling check just... doesn't see the dictionaries at all. (The dictionaries tab eventually links to the second screen, when you can see the pack is installed.) I can't seem to find anywhere else it might need to be activated in first, my computer's default language has also been either dutch or german so that shouldn't have any effect. It's not a restart firefox issue either - it has persisted for a while, i just keep forgetting lol.

I'm trying to switch firefox dev edition to english

There is no dev-edition version in dnf, snap or flatpack, so i simply installed it by hands (from src i guess). But browser is not in english and i don't know how to switch it back. Everything i found related to "lang" is translations and "preferred language to display pages", there is no "browser lang" or smth

Perhaps i can replace some files somewhere in src?

Bonjour J'utilise Firefox et Thunderbird depuis plusieurs années et je contribue modestement au financement de vos activités.

j'ai sélectionné la langue française mais toutes vos explications sont en anglais...? C'est dommage je ne peux profiter de vos nouveaux développements.
