This tool works Rated 4 out of 5 stars

For those who could not get this to work; it is used when you write a comment or a review, within a web page. Then you right click and you will see the menu options. there is no icon. You use when you are the typist; not what you are reading. It works as directed.

Nice tool, also works fine with SeaMonkey 2.35 Rated 4 out of 5 stars

For me works fine with DE SeaMonkey 2.35(γ) (Windows NT 6.1; WOW64; rv:38.0 nightly by Adrian Kalla) Gecko/20100101 Build 20150615204754 (Classic Theme) on German WIN7 64bit.
May be it should be shown as "available for SM 2.35"?

doesn't even deserve one start. NOT working

Rated 1 out of 5 stars

This spell checker is horrible! It comes up with the strangest "spellings" of words not even related to the word I was attempting to spell. Even the leading letter was WRONG!!! I often have to give up & drag out my "Franklin spelling ace" to get the word spelled correctly.

I need this because I'm not English and sadly, it does not work.

United States English no Firefox 36.0.4 Rated 5 out of 5 stars

Instalei este complemento no Firefox 36.0.4 sem nenhum problema. Está funcionando perfeitamente bem. A única dificuldade que encontrei foi com o botão instalar, que não está funcionando! Pedi par abrir em Nova Aba e ai, sim, funcionou sem problema.

Didn't work on Firefox 36.0.4

Not compatible with Android Firefox Rated 1 out of 5 stars

Not compatible with Firefox for Android in version 35 or 36. I would give it 0 stars but that is not possible.

This user has a previous review of this add-on.

Rated 5 out of 5 stars

This is a great add-on! Allows you to check your spelling on sites that don't have their own checker. I simply hit the install button and the thing started working immediately.

Won't Install Rated 1 out of 5 stars

Won't Install! Say's it's not 33 compatible!

It works fine with Fx 33.
Check your system.

Yes but where is "install from file"? Rated 2 out of 5 stars

Yes but where is "install from file"? I've got Add-ons Manage open and there is no longer and "install from file" so how does one really do this now adays?

Perfect Fix! Rated 5 out of 5 stars

I Run LinuxMint 14.04 with Cinnamon twist and couldn't figure out for the life of me why spell check wasn't working. I'm dyslexic so spell check is very useful for me. Glad I found it. I tested it and it works perfectly.

The US-Spellchecker Rated 1 out of 5 stars

I can't load it down!!! Why was it taken away from my Thunderbird?
Why have I now 4 different French spellcheckers?
0 stars for thunderbird!

Works, and well. Rated 5 out of 5 stars

WORKS, and and that includes the British version as well.

You can't use the [download-button] to add the dictionary file to your programme. Or in my case, a new clean thunderbird (ver 31) install.

Give the developers a break, it does all work, but sometimes you have to work at it to get it right. If the button doesn't work, then right click it and download the file->link to a directory.

Go to the add-ons manager, and select install from file (do it from where you saved that *.xpi file)

Accept all warnings. Restart the programme, and - volar' - you now have your spell-checker installed.

Very useful, and free, and just brilliant.

Rubbish Rated 1 out of 5 stars

I can't even download this shit. 1 star is more than enough.

SUCKS! Rated 1 out of 5 stars

I am only giving this add on 1 star because I can't give it 0 stars. You can't even download the GD thing so what the Fxxk good is it.

Что тут за дебилы в комментах по отписались? Один в почтовом клиенте не нашел, другой тупой что не может понять как работает дополнение и ставит 0 - это просто уму не постижимо. Спасибо за дополнение, очень полезно иметь подсказки правописания на английском. Все работает как надо и где надо.
