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.

Doesn't work !

Because it's always essential to have English as the main source of communication.

good

love

Although I live in London, UK, I cannot access this package. I'm stuck with the annoying spelling of the US version.

I'm in uk and can't use GB language add-on? Really!?!?

nie działa angielski, english language does`t work

I have tried on about 3 occasions to change the default language of Firefox from US to UK English. It has never stuck, so the spelling corrections I make when marking student's work are shown as errors.
How can I ensure that the language setting NEVER reverts to US spelling?

Het pakket vult mooi aan wat ik even ben vergeten ...

It is not clear that this package is not for spellchecking

does not work ; english does not appear in the choice of languages for correcting the text

My Great Britain.

Je souhaite harmonisée mon anglais,merci.

It's so nice to not have Firefox telling me to spell words ending in ....ise as .....ize or spelling colour without the 'u'. Now to find out how to make it my default.
