This add-on seems to be overwritten by the English (US) language - very frustrating when the spelling check underlines the correct spelling for English (UK) words in favour of English (US) - exactly like it's done here for 'favour'!

Constantly reverts to US English. This is so annoying that I may well have to ditch Firefox altogether. PLEASE rectify!

It doesn't work...

er, it doesn't seem to want to install on firefox quantum 63.0

Just does not work on Mac. No spell check function at all.

Cannot add this pack in the UK when the pack already has the US version!!
Must go to options and remove the US language to enable the UK pack.

Ghastly! No matter how many times I try to change the spellchecker language from US crap English to proper UK English it doesn't reset it!

Doesn't work. Using British English Marco Pinto instead.

This is useless, disable it in your add-ons and install this one.

British English Dictionary (Marco Pinto) by Marco A.G.Pinto

Problem sorted.

It says I should use the 62th version of Mozilla insted of 60th but this is the 62th.

I would give this zero stars but at least one star has to be clicked on for a review to be made. Why doesn't the English (UK) dictionary work? I see that there are a lot of users commenting the same thing here, so why hasn't this been fixed so that it works? I have also just updated to the latest version of Firefox and the UK dictionary did download apparently but there is nothing there and I am still being corrected to spell things the American way. I am English and want to write in English - not American! Not impressed at all!

Why can't I install any language pack that is relevant to me? I am not from Americaland!!!!

It tells me that I can only install English SA or UK if I have Firefox 62 or newer, and then I click to download the latest version, which turns out to be 61.02 something!!!

How can the minimum requirements be higher than the latest release? That's just screwed up!!!

I DON"T WANT AMERICAN SPELLING!!!!!!!!!!!

Pourquoi dit-on que "Ce module nécessite une version plus récente de Firefox (version 62.0 minimum). Vous utilisez Firefox 61.0."
La version 62.0 existe-t-elle ? J'en doute. En tous les cas le lien présenté ne renvoie pas vers son téléchargement.

does not work

do not work

Terrible. Zero stars. No only does it NOT WORK, but it blanks-out all the text in 'options'.
Does Mozilla bother to read these reviews & fix their damned software? No. Thought not!

Added to Firefox,restart and Facebook is still in ridiculous American English !

Not working or showing up, even while I have it installed.

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.

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