The LanguageTool spell checker APIs are great, but I'm disappointed by the addon:

- adds a lot of noise in dev tools: data attributes, lots of opaque event listeners, dozens of CSS variables.
- I don't need constant nudges to upgrade to premium—I'll do it if I'm happy with the default version.
- the source on GitHub is outdated—where can I find the source for the new addon?

Kind of a useless addon... it takes you to a website where you can see the errors but it does not clearly show the correct spelling of those words.

It is far quicker just to use another service such as google.

Sadly no Indonesian, Javanese, and Balinese language option in this spell checker extension.

This used to work brilliantly. However, it now only highlights grammar and spelling mistakes as clicking on suggestions no longer replaces the misspelled word or corrects the grammar.
I have removed and re-installed twice to try and fix this fault to no avail.
It is now of minimal use.

Pour faire un test j'ai écrit une phrase contenant 6 fautes d'orthographe, et le correcteur ne m'en a signalé que 3, pour une note de 50%. Plutôt inutile!

Refuses to work no matter what I do. I have tried Restart Firefox, delete and reinstall the extension, Delete the extension then uninstall Firefox then reinstall Firefox then the extension. Nothing worked.

I don't get it. In basic mode the ad-don does nothing. Right click on selected text opens new tab with misspelled word highlighted. And that's it. The misspelled word never gets replaced...and it shouldn't open a new tab either...as it is, it's useless. Please advise. Thank you...

Absolutely fantastic piece of software, except for when it stops working entirely to push you an incredibly unsubtle ad for their premium service.

This addon is good but has some disadvantages burdens the operation of the browser and so websites, :-( while I would like such problems with this extension was not and I hope that over time it will change for the better by making another very large update : - )

It is barely more useful than the default spell checker. What I wanted from this is an auto-detect for auto-switching languages. It hasn't implemented it. It also doesn't show the squiggly lines and is quite buggy.

But above all, it uploads every keystroke to its corporate servers... So... uninstall immediately, how bloated and intrusive is that? No thank you, either take all the code to the client add-on or don't make a spelling add-on at all....

Generally a good extension, but unfortunately not available for Android.

LanguageTool corrects me:

El niño esta en la guardería

The right thing is:

El niño está en la guardería

other,

I write:

eso esta echo

LanguageTool:

eso esta echo

The right thing is:

Eso está hecho

In Spanish the extension is still green, but it is a good idea
