CloseReview for Grammar and Spell Checker — LanguageTool by philby
Rated 5 out of 5 stars
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.
This review is for a previous version of the add-on (4.2.12).To create your own collections, you must have a Mozilla Add-ons account.
