Way to choose profit over user base. Grammar tools have existed long before generative AI and will continue to exist for long after. Extension works well, but not worth paying premium. Do better.

Premium only => Go to hell

"We've made the difficult decision to limit the LanguageTool browser extension to Premium users only".

BYE.

It is no longer a free add-on. And they ask like 15$/month for using it. Ridiculous! So long, and thanks for all the fish!

It was a free tool. Now it suddenly needs to paid for. NEXT!

It's paid extension now - don't bother getting it

Getting rid of the free plan will be the worst decision you ever made.

As from May 2026 it's now a premium feature.

Après des années d'utilisation je désinstalle à cause du changement de politique tarifaire et de produit. Il me faut un simple correcteur d'orthographe (ce que vous faisiez excellemment bien) pas un assistant IA (encore un) qui me coûte plus cher que mon antivirus. Imposer la version premium payantes à celles et ceux qui n'en ont pas le besoin vous prive de votre principal outil de promotion.
Vous avez le meilleur correcteur d'orthographe que je connaisse, dommage de vous tirez un bal dans le pied comme ça...

Preferia a ausência de recursos de IA para manter grátis. Ao menos oferecer um plano sem IA, com um preço mais acessível, recomendei para varios amigos e agora recomendo desinstalarem a extensão.

asks you to pay after a time limit make sure to take it off after you have tested it its bogging down the browser otherwise. cant recomend 1 star

requires a paid plan to use.

There is clearly a significant memory leak issue on Firefox. As a paid subscriber, I am no longer able to use it. Firefox freezes and becomes unusable.

I am a premium user, and unfortunately the Firefox extension is causing serious issues. It consumes up to 32 GB of RAM, which makes my computer freeze and eventually restart on its own. This is not an isolated case — it happens on two different computers, so it’s clearly not a hardware issue on my side.

This makes the extension completely unusable despite paying for the premium service. I would expect much better stability and performance from a paid product. Please investigate and fix this as soon as possible.

It used to be a 5 stars plugin, but since the January 2026 update, whenever I switch this plugin on, firefox crashes on my Macbook. It totally eats all the memory. I reported it as a bug more than a month ago but haven't heard from them. So, for now, it will stay switched off.

It's even worse than the built in spell checking of FF.

It isn't shown on here, but if you click the link in their "about" section, you can see that they now use AI to scan and check your text, which is probably why I've been getting so many errors in it lately, including ones for proper nouns that weren't there before.

In short, don't use it. It doesn't work like it used it, and as it is using AI, there is the potential for it to be using your own text to train models. Uninstall it if you have it already.
