"strict_max_version": "142.*"

Why the hell do you set a MAX version, when Nightly uses v143? I can't use a fucking language pack because I use a newer version?

Werkt niet.

For everyone looking for the actual language pack that shows up correctly in your options: its here: 03.yfhome.xyz/en-GB/firefox/addon/british-english-dictionary-gb/
i dont know what this is meant to do, but it sure doesn't show up as a language to pick. even when restarting firefox. however the above link worked first try.

Downloaded and switched to English (GB) in my Firefox settings but it still uses English (US) :/

Does not work: always defaults to US English. Very annoying.

Even though I've installed the plug in, Firefox still uses US English and it's diving me nuts! Very frustrating experience.

This is NOT British English.
realise or realize? British is realise, American is realize. So why does it say realise is wrong? And there are a bunch of other British words labeled as wrong.

Not compatible?

This pack is broken, it will not work on new versions of Firefox.

You need to instead use: https://03.yfhome.xyz/en-GB/firefox/addon/british-english-dictionary-gb/

Installed but nothing changes and only en-us is available

These language packs don't work in FF on my new MacBook Air. I add German, French and English just like previously - but in the browser I cannot select English and checks don't work

It doesn't work. It's installed but doesn't show up in the UI whan I want to use it.

This somehow doesn't work at all. It says it was updated 18 days ago and yet it's broken for according to the other reviewers months now! Weird...

Can never be apply to any website....

> This add-on is not compatible with your version of Firefox.

No point in having an add-in that never ever gets applied to any websites.
