Must have

Much better than nothing, but not perfect Rated 3 out of 5 stars

A basic test with Firefox 57:
1) Color? OR Colour?
2) Favor? OR Favour?
3) Favorite? OR Favourite?
Bizarrely, while typing this I get squiggly red underlines on both "Colour" and "Favour" but NOT on "Favourite"! But also, "favour" seems acceptable, and as for "colour"? That works, too. What kind of English dictionary allows a word in lowercase, but not capitalised? -[ uh-oh, that wasn't recognised either! (but "recognised" was!) ]- with initial caps?

Perhaps Firefox remembers my saved spelling for "Favourite", from my using "Add to dictionary"? Well, to test the theory, let's add "Favour" ... that worked. And "Colour" …? Yep, that worked, too. Sigh. Guess I'll have to add capitalised (yes, that's the right spelling!) words to this dictionary individually …!

Cameron, where are you when we need you?

Also, a tiny peeve: Why wouldn't an Aussie spell-checker mark the American spellings wrong? I can think of two likely answers: (1) That might be too hard, depending on Mozilla's implementation of language variants (say they might allow everything in the "main" language dictionary, and ALSO anything in the "variant" or "dialect" dictionary) - which would be a pity, since we then end up with a Not-Quite-Right spelling for our variant of the language; OR (2) They aren't wrong - just less common. Historically, different Australian States taught different spelling systems in school (e.g. NSW used "-or" endings while VIC and TAS used "-our"), tho' I believe that may have changed with the common curriculum reforms. But in that case, a standard reference, such as the Macquarie Dictionary of Australian English, could be used as arbiter.

Mozilla, PLEASE let's have language variants properly supported by their individual dictionaries having primacy! E.g. en-GB should allow only those spellings used as standard in Great Britain; likewise for Australia, Canada, New Zealand, South Africa and anywhere else that officially recognises an English-language variant. Also applies to other language groups and their variants.

Abandoned - but can be installed Rated 3 out of 5 stars

Cameron's website is gone si I am guessing that this dictionary is abandoned. If I could figure out how to take the extension over, I would because the fix to make it install on Thunderbird 45 is trivial.
Here is what I did:-
1. Download the extension to local hard disk.
2. Using an archive manager, extract the files to its own directory.
3. Edit install.rdf and adjust the following lines:
- em:version 2.2 /em:version
+ em:version 2.2.1 /em:version
!-- Firefox --
- em:maxVersion 33.* /em:maxVersion
+ em:maxVersion 50.* /em:maxVersion
!-- Thunderbird --
- em:maxVersion 33.* /em:maxVersion
+ em:maxVersion 45.* /em:maxVersion
4. Save file
5. Edit install.js and adjust the following line:
- var err = initInstall("English (Australian) Dictionary", "en-AU@dictionaries.addons.mozilla.org", "2.2");
+ var err = initInstall("English (Australian) Dictionary", "en-AU@dictionaries.addons.mozilla.org", "2.2.1");
6. Save file
7. Select all files and "dictionaries" folder and create a new zip file.
Make sure it uses "deflate" as the compression type.
I called the zip file english_australian_dictionary-2.2.1-tb+sm+fx.xpi which is just a rename of the saved zip file changing .zip to .xpi
8. Go into thunderbird add-ons and using the little gear icon, select "Install Add-on from File", choose the new xpi file and it will install.
By the way, it also seems to work in Firefox 50.x

Gets the red out Rated 5 out of 5 stars

I blog and this is a blessing to getting rid of the red squiggly lines ...

Why is it not supported for Thunderbird 38.5.1? Rated 1 out of 5 stars

I was very disappointed to NOT be able to download the Australian dictionary. So over US spelling and red lines... I ended up downloading the British one to get some sanity back...

Ridiculous! Rated 1 out of 5 stars

Why is this dictionary not available for Thunderbird 38.5? It's ridiculous having to put up with underlinings of correct spelling!

Great Dictionary, Poor Firefox Rated 5 out of 5 stars

Thanks so much to Pijuvwy for supplying the info on how to get the dictionary working.

Poor form on Firefox for forcing all the 'trouble' and 'hassle' getting this to work.

All great now.

A fantastic piece of work by Cameron though, great to not have to constantly have to spell stuff the American way or have 'errors' on your page.

How to fix it: Making the Australian dictionary work! Rated 5 out of 5 stars

So, I found how to fix it. The problem isn't in the dictionary; it's in Firefox refusing to un-Americanise itself. Solution:

Download Agent Ransack. You need this to search for files properly. Search the term "dictionaries:. You'll find a few folders with that name. One of them will contain only US English files ( en-US.aff and en-US.dic ) if your Firefox refused to use the Australian dictionary. For me the folder was C:\Program Files (x86)\Comodo\IceDragon because that's the version of Firefox I was trying to fix. Open the folder.

Also open the folder that DOES contain your Australian dictionary files ( en-AU.aff and en-AU.dic ). For me that was in an extensions folder, among other places.

Now, copy your Australian dictionary files into the folder containing your American files. Almost finished.

Next, to be sure, rename your American files. I added .was to give them a new file extension that would be easy to reverse if necessary.

NOTE: You'll need administrator access to move the files. You'll need to have file extensions visible (set that in Folder Options control panel).

WHAT THE HELL?!?! Rated 1 out of 5 stars

Appalling. I have no idea why this exists. It can't even get simple EUROPEAN spelling of words such as Favour/Favourite, colourful (DESPITE THOSE BEING IN THE FRIGGING DESCRIPTION!!!) or even BLOODY METRE CORRECT!
I am completely flabbergasted that this exists. It is entirely useless, and clearly all of the reviews have come from people that are ENTIRELY ILLITERATE.
I'm certain that this was uploaded as a joke. GAOL <- EFFING RED LINED! ARE YOU KIDDING ME?!?!?!?!
Ultimate test: Aluminium. Can you guess if it got red lined or not?

Rated 5 out of 5 stars

Why is this not a Firefox language by default?

Awesome! Rated 5 out of 5 stars

This is great! Installed easily and quickly in a set-and-forget manner. It's great having less of those red lines! One thing though - It marks "anymore" wrong. Other than that, great!

Thank you! Rated 5 out of 5 stars

Installed effortlessly to Thunderbird, so glad to have a true Aussie dictionary. Thank you for your work, it's greatly appreciated :)

Compatibility Rated 5 out of 5 stars

This works in Fx 34 -- I edited the install RDF file to bump the Fx max version number to ensure it will install and work.
That is all that is needed to make this work for newer Fx versions

PLEASE update this! Rated 1 out of 5 stars

I love having this dictionary, and although it still seems to work on my old PC, even though I have updated TB to the latest 24.2, it won't let me download it on my new computer, so now I have no dictionary at all! Are you still supporting this add on? As far as I can see, you haven't updated it since 2011?

This review is for a previous version of the add-on (2.1.2). 

No updates to the dictionary's code have been required since 2011. I have just bumped the compatibility version for TB so perhaps restart TB/FF and try again.

What's the point? Rated 2 out of 5 stars

I've got the Australian dictionary in my number 1 slot (in preferences), British in number 2, and have removed the American dictionary, but Firefox still spellchecks my pages in US English by default. So what's the point trying to fix Firefox spelling setup with installed dictionaries?

Colour I want not Color. Rated 5 out of 5 stars

I agree with the developer completely. However, I am actually waiting for the English (British) dictionary to be ready for my Thunderbird 15. But for the time being my Australian friend will be of great help to me for my colours will not be marked red.

Rated 5 out of 5 stars

One of my *favourite* add-ons for Firefox. The English (Australian) Dictionary prevents Australian English words being marked as incorrect. Before I had the add-on, I wasted time second-guessing my spelling because of that little wiggly, red line; even if I was certain I'd spelled a word correctly, I double-checked it every time. How annoying!! Luckily, I found this add-on, and it's been brilliant ever since. I don't have to ignore all the red wiggly lines now; it picks up my actual typos, and has saved me many times from posting incorrectly-spelled words online. I can't recommend the English (Australian) Dictionary for Firefox more highly to anyone who uses Australian English spelling.

Rated 5 out of 5 stars

This plugin delivers exactly what it promises: a functional spell-check dictionary for Firefox. Works just fine with FF 12.0.

As an aside, I've found that this dictionary is quite a bit better for us Canadians who are used to the older Commonwealth spellings - so if you're a Canuck looking for a spell-checker that isn't rife with Americanisms, look no further.
