  • I have tried this and that, have read and re-read instructions, and keep going round in circles.

    There isn't much magic in the process:
    1) right-click in the "add to Firefox" button;
    2) Save the file to the hard disk;
    3) Open the target folder and drag the file to the Desktop (or save it there directly);
    4) Open Firefox and go to the menu: Tools > Add-ons;
    5) Left-click in the downloaded file and drag it into the Firefox add-ons window;
    6) Accept the installation;
    7) Right-click in an editable text area, for example: try it here when you are going to increase your rate to 5 stars, Select: Languages > English (United Kingdom) in the pop-up menu.


    Not much magic in it.

    Please try it and send me a private e-mail if you need any further help.

    EDIT: If you have already the GB speller from the other guy, you need to remove it as it will conflict with mine.

  • fixed my spell checker problems in facebook

  • tres pratique et rapide

  • the extension is installed, but how to download the dictionary ? any link please?

    Developer response


    If the extension is installed, the extension is the dictionary.

    You just need to turn it on:

    See points:
    3.1 & 3.2

    And remember that to use it in Thunderbird, you will need to install it there.

    To use it in Firefox, you need to install it there.

    (to use on both, you need to install on both).

  • I've followed the FAQ but it doesn't spell check anything and all words come up underlined. Yes, I have selected English (GB) in the spell check settings; yes, I have uninstalled any other dictionaries (I even removed the Firefox GB Language pack as well); I've tried uninstalling and reinstalling several times with no change.

    I've had to go back to the standard GB Language pack with a (bizarrely) US dictionary - at least the majority of words are checked now :-(

    Can't reply to the comment below directly but I've tried manually installing the addin as per the instructions but there is no difference.

    EDIT 2:
    Yes, as mentioned in the original post, I have selected the Dictionary/Language for Spellchecking in an editable field - This is when it switches from just highlighting non-US words to highlighting every word so I know it's made the switch (It just doesn't accept any words as spelled correctly).

    Hello Zog,

    Could you try the steps explained in:

    Please tell me if this solves your issue.


    EDIT: Make sure you have installed on Firefox if it is to be used there. Then, right-click in an editable text area just like this one when you writing in it, and select: "Languages" -> "English (United Kingdom)"

  • I don't know how to use this add on. I've installed this one along with Google translate extension. When double click on any word, only the translate extension pops up. Please guide me.

    I have written a page explaining how to install and activate:

    I hope this helps.

  • Best up to date British English spelling extension for Mozilla there is!

  • Very good.

  • This add-on seems very good, though one thing I have noticed that it has only 60 of the 66 books of the Bible. I would like to request the six missing books, which are: Habakkuk, Malachi, Philippians, Colossians, Thessalonians, Philemon. As a Christian, I talk about these books constantly. It is also a shame that the add-on doesn't include American spellings such as color. When I'm not speaking to Brits, I prefer to use American English, so as not to create any barriers in communication.

    Developer response


    I can't add "color" since it is American, but you can use American words by installing a US speller and toggling between spellers as needed.

    Tomorrow morning I will work on the six bible missing books.

    I will try to find if Wikipedia has information about them in order to try to find missing related words.

    Consider that on Friday night I will update the nightly changes in GitHub with missing bible terms:

    Thank you!

    Kind regards,

    Tons of bible related words/names added.
    See the GitHub release notes for 16-FEB-2018.
    It will be available in the monthly update within a couple of weeks.

  • Simple and user friendly interface.

  • Best thing since malt whiskey was invented

  • great work!

  • Works well in Thunderbird, rather ironic that I had to create this review in order to create an 'editable text box' so I could enable the dictionary in Firefox!

    Developer response


  • Love British spelling. Thank you.

  • Great add-on, thank you for this.

  • Excellent plug in. Thank you for all your hard work.

  • This is a breath of fresh air from the stifeld suffocating reach of google and its affiliates stealing everything you are and leaving you with nothing to conceal our identity like a newborn naked baby with no protection this the quick cure all the keys to freedom in anonymity I want you thank Firefox and it's team godspeed God blessing get Ghost

  • Thank you for maintaining and updating this educative extension! Working perfectly in Pale Moon.

    Developer response


    There is still a long way to go, I believe, but as long as I live I will keep on improving it.

    Starting on 2-DEC I will continue adding possessives to proper names, as I have only fixed the missing ones in the letters A-G... thousands missing I believe.

    Always remember that if you or anyone find any missing words that exist in the Oxford/Collins dictionaries, just send me an e-mail for analysis.

  • To enable, right-click in a text box, select "Languages", then "English (United Kingdom)".

    What's/Where's a "text box"?

    Why do I need a dictionary to be able to understand how to use your dictionary.

    Found it. This must be a text box because the Languages option has just shown up.

    So easy...NOT.

    Hello KES,

    The detailed instructions on how to install/use are explained in:
    (there was a link in the add-on description to it)

    Could you please increase the stars since you missed the link above and I have spent full days adding words to it and also writing the FAQ/instructions?

    Thank you!

    Kind regards,

    I have just improved the add-on text to match your suggestion:
    "To enable, right-click in an editable text area, select "Languages" → "English (United Kingdom)"."
    Is this easier to understand now?

  • Nice

  • Correction on spellings when typing word

  • nice
