FAQ ("movie", "automobile", "airplane", "hardcover" and "bookstore"):
Notice: Due to complaints, "movie" was added on V2.57 since it is a widely used word.
Nightly changes (GitHub):
This GB speller is Mozilla's official one :
Just like in other languages, some words can be written differently. Since Oxford says some words are valid both ways, I kept both and the user decides which he prefers. A good example is: "online" and "on-line".
For ize/ise, both ways are accepted in some words:
— optimize/optimise: https://en.oxforddictionaries.com/definition/optimize;
— realize/realise: https://en.oxforddictionaries.com/definition/realize.
Oxford Dictionaries will only refer that certain words accept both ize/ise for Premium accounts.
The regular user won't know by accessing the Oxford site, but I have access to it.
Places from New Zealand/UK (England, Scotland, Wales & Northern Ireland):
On V2.61–2.64 I included tons of place names.
My scientist friend, Peter McGavin, told me that in NZ they use British, so I decided to do something about it. I did the same for UK. I searched on Wikipedia for "towns", "counties", "villages", "boroughs", "suburbs", etc. and based me on:
Also, added places sent to me by Peter C.:

Cities from Australia
On V2.65 I added the cities in Australia by population, since they are in valid English:
Cities from US
On V2.65 I added tons of cities in the US with a 10 000+ population, since they are in valid English.
This list was supplied by Michael Holroyd on Kevin Atkinson's GitHub.
Cities from Canada
On V2.67 I added the cities in Canada, since they are in valid English:
Common prescription and OTC drugs
On V2.63 I added tons of drugs names supplied by Andrew Ziem on Kevin Atkinson's GitHub.
The generic drugs (such as "diphenhydramine") are in lowercase, while the brand names (such as "Abilify") are capitalised.
Main difficulties developing this dictionary:
1) Proper names;
2) Possessive forms;
Adding new words:
If you believe to have found a missing/incorrect word, please send it to me for analysis. If it is on the Oxford or Collins dictionaries, I will add it.
I developed Proofing Tool GUI (open-source tool) hoping someone would improve the GB speller, but months went by and no one volunteered, so I took the task myself in 2013.
I have created the best up-to-date British speller. It encompasses several fields of knowledge, from simple to complex words.
It doesn't matter your religion, sex, age or academic background, everyone should have access to all words equally for free.
To make sure the words I add are the correct ones, I have been looking for them in credible sources:
1) Oxford Dictionaries;
2) Collins Dictionary;
3) Macmillan Dictionary;
4) Cambridge Dictionary;
5) Merriam-Webster Dictionary (used with caution ⚠);
6) Wiktionary (used with caution ⚠);
7) Wikipedia (used with caution ⚠);
8) Physical dictionaries.
In January 2015 I purchased an "Oxford Gold Account" to have a higher access in Oxford Dictionaries.
I am also involved on several projects with a specific jargon having added some "special" words.
I am adding the words with copy/paste after checking them in the dictionaries mentioned above. This is slower and harder, but the results are much better and accurate.
On 25.Aug.2013 I released a "forked" V2.00. The speller has been made available to OpenOffice, LibreOffice, Firefox, Thunderbird and SeaMonkey. So far, I have added 84 232 words (as of V2.71).
