The finnish dictionary did not seem to work(moz 1.4) it because fi.aff is missing??

Really looking forward to checking my spelling in finnish.

Did it fail to install?!

[6] Submitted by: TR, Finland Tuesday November 4th 2003

No, not at all, it installed fine. When checking spelling in Finnish it either says "no misspelled words" or goes through every word and suggests really funny corrections. The prior has been tested on two different computers with win2000pro (moz 1.5 and 1.4). Here is a misspelled Finnish sentence:

Autola pyystyy ajjamaan kovvaa kum painna kasua paljjon, muttta siloin sattaa kolaroita esimmerkiksi puuun kansssa.

This is how it should be spelled:

Autolla pystyy ajamaan kovaa kun painaa kaasua paljon, mutta silloin saattaa kolaroida esimerkiksi puun kanssa.

It seems to not work without the affix-file. :( After checking with another dictionary (Swedish) it seems to think all words in the correct text is misspelled.

What about Thunderbird ?

Does this work with Thunderbird too ?
Spell checking is nice in a browser... but even more interesting in a MUA ;)

It works without any problem in TB too. Once you have installed it for FB, all you have to do is to copy XXX.dic and XXX.aff files from Firebird/compomnents/myspell into Thunderbird/compomnents/myspell. I use it for two weeks (TB-0.3, Win-XP, [Russian,Swedish,EnglishUS,German]) and everything works fine!

so is the en-US version here newer/bigger/better than what is included in the moz 1.5 build?


[12] Submitted by: rockstiff Thursday November 20th 2003

The US dict is the one found on It's file size was bigger, so it should be better right?! ;) I think it's newer, but I'm note sure...

To install in Thunderbird you don't have to install inte Firebird first... just follow the instructions on the installation page! Good luck!

Install the Spell Checker for Firefox:

The download function does not work for my Mozilla 1.6 Installation.

Download the file and open it using Mozilla (File - Open File). When doing this, it installed fine!

Other than that - great stuff!

What kind of file Editor should i use to view and change your dictionary files ?????
I have Win 98 on my computer !

I should help ifonly i can see the files INSIDE 's ;O)

[18] Submitted by: rockstiff Monday March 8th 2004

xpi-files are renamed zip-files... open them with your fav archiver and extract the files. The files inside are readable with any text editor.

Hi fellows,
where can I get a Turkish spell checker?

[22] Submitted by: marcin Sunday April 11th 2004

Thunderbird 0.4 - Polish spell-check is called just pl-PL (yes, I have changed underscore to hyphen in both files' names, worked for all English and German files, but not Polish).

[23] Submitted by: marcin Sunday April 11th 2004

Re [22] - I see my error, filenames should be only pl.*, not pl-PL.*. Sorry for the mixup (maybe you can delete both my entires).

When I run a spell check using the British dictionary, it doesn't complain about the word optimization, it should be optimisation.

When I install the spelling checker in windows ther is nothing wrong.
When I install the checker using Fedora core 1 i can only install when I'm locked in as root. I works fine then.
Only I cannot install spelling checker when I'm locked i unther my own account.
It's says 'installed" but ther is no new spelling checker installed. Only the default.

Few days ago I ported our Hspell (Hebrew spellchecker) dictionary from

to mozilla. The package may currently be accessed from

I would like to contribute this package to the mozilla project (it is GPL).

I had to edit your install.js script slightly, so that it warns the user if the installation fails due to permissions problems. You may wish to include this change in other dictionary packages.

Also, in the Language listbox of the Check Spelling dialog, the dictionary appears under the name of the file (he-IL) and not "Hebrew" or "Hebrew / Israel". Are these strings hard-coded into mozilla, or should I supply it somehow with my dictionary?

Another question I've got is regarding bilingual spelling. Is there a way to allow for two langauges in a document?

I took a look at the swedish and finnish dictionaries available here. The swedish .dic is all ascii, a word list basically. Finnish one has a disclaimer to be from the Soikko project, and the rest is binary.

Soikko has a wrapper for linux (Tmispell) that makes it ispell-compatible, which in turn should be convertable to myspell. Anyone up to the task?

I tried the Swedish spellchecker for Thunderbird. I'm not sure if it's the newest version. I just took the one I found on this page.

It was not very useful. It "corrects" prefectly correct words with misspelled ones like "uppdaterad" to "upp daterad". It also lacks many common wordsm, and don't seem to be able to check Swedish grammar. That might be why I get some of these errors.

However this is still a very good project, and I hope it will grow bigger with more contributors. I would wish for a Japanese dictionary, but can't contribute myself (for the obvious reason that I need it so that I can write some decent Japanese in the first place). If somebody could convert/use EDICT that would be a great startingpoint!

Anyhow, keep up the good work!

It'd be nice if the dictionaries used Tb 0.7's extension management system properly, so users wouldn't have to reinstall every time they upgrade.

Congrats for the project. Just one question/suggestion:
is it possible to use for Mozilla the same dictionaries (personal dictionaries included) that are used in If yes, how?

Yes it is, its actually the same dict. as the ones here. Just copy the dict-files to the myspell directory under components.

I just sent you a repackaged version of the spell-en-US.xpi which includes the 06-23-2004 update to the English Dictionary.

I have no good knowledge about the Extension Manger System yet since i've still new to Mozilla and FireFox which has an Extension called Spellbound that uses your dictionaries. :).

I may be wasting your time with a dumb newbie question - apologies if I am.

I noticed a comment on the page that the spell checker used for UK English uses the same dictionary as OpenOffice. Given that OpenOffice has a good Afrikaans dictionary, would there be an option to have an Afrikaans spell checker for Thunderbird too?

Many thanks in advance
Thunderbird 0.7.3, Firefox 0.9.3

Trust me to ask the question, then have my morning coffee, and only then think for myself :)

I renamed the from Open Office to Af_ZA.xpi, installed it as an extension and copied the Af_ZA.aff and Af_ZA.dic from OO to the Mozilla Thunderbird/Componenets/Myspell directory and hey presto - Afrikaans as a spell checker!

Thank you for a wonderful resource

When you use the spellchecker in Thunderbird it invites you to make downloads from It would be very helpfull to give a hint on this page that you need to copy the download after installing from Firebird/compomnents/myspell into Thunderbird/compomnents/myspell. Otherwise newbies like me need 24 hours to find out! :-)
