LT requires the following permission: Access your data for all websites. According to Firefox support the permission allows LT to "read the content of any web page you visit, as well as data you enter into those web pages, such as usernames and passwords" That is too much risk to give to a spelling and grammar checker

This addon is great but only works for first 20 words in the day, is trash need buy a pro version for this trash

They can see everything you write, and they record that unencrypted data. I should never have even tried this.

Has become very stupid. Makes incorrect "corrections" constantly, gets tense wrong, does not know words exist (it tried to correct 'withering' to 'dithering' for no reason). Used it for a while but have had to stop because it's irritating more than helping.

Does not work with custom server anymore.
Does not even send a request and then times out.
It works with 8.11.2 so I reverted to that one.

Edit:
8.13.2 also works, so seems like you introduced a problem when updating to 8.14 which seems to have been a major update.
I went with 8.11.2 first because that was the version that is currently still working in thunderbird.
Not really keen on making an account just to report it.

The amount of times it suggests changing the tense to be incorrect is staggering. Sometimes I will accept its suggestion, then it immediately changes its mind and suggests I undo its suggestion. It also strongly suggests breaking sentences up to be grammatically incorrect. It is consistently dumb and only gets it right 50% of the time. I can't recommend it.

Breaks spell checking completely, now nothing is being spell check at all!

Not a very smart spell checker.

bye-bye AI trash

Anfangs absolut top, mittlerweile aber so grottenschlecht.. Ständige endlosloops, Fallfehler ohne Ende die am Anfang nicht da waren. Ich habe das Gefühl, dass Programm wird dümmer und dümmer jeden Tag den ich es nutze.

Another AI slop that tracks you everywhere and steals your data. Avoid at all cost

Uninstalled after they integrated AI trash into this tool that I don't want or need, and updated their privacy policy to reveal they're tracking you across the internet so they can train their worthless AI. Only reason I switched to this from Grammarly was to avoid tracking. Enshittification is real, and it's hit this extension.

Used to be amazing, now it's yet another AI filled mush of a software because they want to be on the badwagon too.

I'm using this for writing. Why the hell would I want an AI built on the theft of people's work given access to my writing and telling me what to write instead. Uninstalled with haste.

PRIVACY POLICY UPDATED TO TRACK YOU, AVOID

No automatic correction option, only reason I tried it.

no ai bs plz

Don't care for it.

Kept telling me "1 More Writing Issue Found" and hid it behind a paywall with no way for me to disable it.

What this means is on half of everything I end up typing, it ends up going orange as if I've made a typing error.

But I can't see it unless I pay.

If they just didn't make that orange, I'd be ok.

I'm not paying for something that literally annoys you until you pay for it, and I won't use something like this that won't let me disable or hide suggestions I can't view unless I pay.

Maybe I would have payed if it quietly and politely suggested there was another issue I could fix, but I refuse to pay for it when the developers use annoyance to try and get users to pay.

Uninstalled.

Will legitimately not work for me, no matter what I try. It tells me that I have not written enough (minimum of 5 characters) even when I have written hundreds of words, and it will not update at all. Completely useless.
