I cannot get get spell check on yahoo mail

Does not work AT ALL ! English does not even appear in the list of available languages to be used... (English US the same, btw).

This must be the WORST English language pack around, maybe created by a NON English.
Lost of worths missing even my 5 year old daughter can do better.

FACILE A UTILISER

This language pack claims to check English (GB), but it seems to have been written by an American.
Far too many spelling issues that prefer the American spelling to the proper British spelling.
If I had wanted American spelling, I would have opted to install the English (US) Language Pack instead.
Silly.

Ok

Strangely, it installs but does not show up on the right-click context menu of available languages.

Have tried several times and, like so many others have said, it doesn't work! We are in the UK and are stuck with US spelling and keyboard - can't find the pound symbol, @ is in the wrong place, etc etc! PLEASE fix this...

https://addons.mozilla.org/firefox/downloads/file/1005504/english_gb_language_pack-61.0buildid20180704003137-fx.xpi?src=dp-btn-primary redirects to https://addons.mozilla.org/en-GB/firefox/addon/english-gb-language-pack/ so the language pack cannot be installed.

Doesn't work !

super ok ce dico

does FF not read this?? .
this is not taking your users very seriously, reading the many 1-star ratings all with the same reason:
IT DOES NOT WORK ;((((((

Tells me my version of FF is too old even though I've just installed the latest version

It does not appear to work, now whether this is a fault of Gmail (yuk I hate it but that's what the company uses) or not I don't know, when typing words in to Gmail where it expects a "z" and I use an "s" I get a spelling error.

Does what it is supposed to do.
