I attempted to install this Add-on in my Thunderbird 9.9.1 but McAfee stopped it and said that this is a virus. McAfee quarantined the script file. How do i know that this is not a virus or a trojan?

All add-ons on this site are reviewed by Thunderbird, so you can safely assume that McAfee gives a false alarm here.

I am so glad I found this extension. Grammarly is just awful. I used Grammarly when it first came out and love it. As the system is learning and especially in the last six months to a year it's been so awful. It takes more time to fix Grammarly mistakes in my documents. I'm using this extension from hereon out. Fingers crossed it stays true to how it is now and doesn't progress into what has happened to Grammarly.

Bonjour,
S'il vous plaît, faites vérifier ce module par Mozilla, il ne peut pas être installé dans Thunderbird s'il n'est pas autorisé. Idem pour emoji 1 91 8 tb xpi
J'utilise le module pour Firefox, il est FORMIDABLE ! Bravo !

The corrector does not work fine.

Could you tell us what exactly didn't work for you?

It is that spell check going to the cloud, scanned and sent back or is it an offline tool like the old thunderbird spellchecker? It is a bit scary the "online" part.

This review is for a previous version of the add-on (4.4.0). 

This is documented in the description at https://addons.thunderbird.net/en-US/thunderbird/addon/grammar-and-spell-checker/: by default, the cloud is used and there's a privacy policy which describes the details. You can also run the server locally.

It requires "full, unrestricted access to Thunderbird, and your computer", which seems way too much.

There's no way we can check your text without that permission.

The LanguageTool plugin works well; however, I have noticed that this plugin is inferior to the LanguageTool editor. I can apply all corrections from the plugin, then paste the corrected text in the editor and find additional corrections. I would have expected the same performance for both the editor and the plugin.

Note: I found the same issue with the Firefox plugin and added the same comment there.

This review is for a previous version of the add-on (4.2.12). 

The editor and the add-on use the same backend (unless you use a local server), so the results are the same. You might have enabled picky mode in the editor, but not in the TB add-on. If you still see differences, please contact our support (see https://languagetool.org/legal for our email address).

Excellent!
I run a local server as explained on https://dev.languagetool.org/http-server. This way, Thunderbird, LibreOffice and Firefox use the same server, and LanguageTool works offline.
The proposed corrections in English and French always make sense and go far beyond native correction tools.

Thank you for bringing this add-on to TB - it helps greatly, especially if you need to constantly switch between multiple languages for multilingual communication. However, there seems to be an issue with this add-on - it does not allow to disable Thunderbird's spellchecker. Even though the Spelling options are switched off in Thunderbird, with this add-on ON Thunderbird underlines misspelled words in a composition window. If you uninstall this add-on all goes back to normal - no more underlines with TB's spelling OFF. Please fix this issue and I will be happy to give 5 stars :-). Otherwise this addon creates double marking for misspelled words which makes the text hard to work with.

UPDATE (29.11.2021) - Thank you for your quick reply. I've just sent all the requested details to your support email address. Looking forward to your feedback.

Sorry this doesn't work for you. Could you contact our support using the email you can find at https://languagetool.org/legal and send a screenshot, the TB version you use, and your operating system?

My favorite spell & grammar checker, finally on Thunderbird! I was waiting so long for this. If English is not the only language you use, there is no competitor.

The LT checking is not perfect, but from my perspective it's constantly being improved. I also like the open source approach (including adding grammar rules), and I'm recommending everyone supporting their development.

A great addition to Thunderbird and a worthwhile update with respect to the standard spell checker on my pc.
By default, your spelling is checked remotely, but a locally hosted version is available if you are worried about your privacy. If the setup process of the local host implementation were easier, it would get 5 stars from me.

The only grammar check addon for Thunderbird in Linux even when other popular grammar tools like Grammarly, ProWriting Aid etc show no interest in supporting Thunderbird.

Automatic Five Stars for being the only thunderbird add-on of its kind!

"LT works but has disabled other add-ons in Thunderbird, like QuickText."

Thanks for your earlier comment @christopher Blum.
Yes, as soon as I add the LanguageTool add-on, the QuickText add-on stops working.

This review is for a previous version of the add-on (4.1.1).  This user has a previous review of this add-on.

We are still unable to replicate this. Is it a specific function of QuickText that does not work or is it the entire add-on? Please contact us at feedback@languagetool.org. Thank you!

LanguageTool is a mediocre grammar checker. I can't say I recommend the paid license, but the free plan is a welcome step up from vanilla spell checkers.

This add-on is excellent, however. Very responsive, and well designed. Only limited by the capabilities of LanguageTool itself.

Note, that you should be comfortable trusting a third-party with your privacy before using this tool. You can self-host the LanguageTool service, but by default it will send all of your composed email contents through the LanguageTool public API.
