Absolutely working as intended. Had no issues.

Not bad but it cannot spell Bisglycinate or Allulose, Magnesium Bisglycinate from Magnesium and Allulose the natural sweetener.

What else can the AI not spell? That's why I took some stars off, because it cannot learn words, or slang talk.

Edit-

I just found out this cannot spell check for a paragraph that exceeds a certain amount of words, it's a lot but it has a limit, on the other side of why I don't like this addon anymore is it no longer supports windows 7, as I have updated my firefox on windows 7 this app says an updated version of firefox is needed for this extension.

I think it's a nice try for small spelling check, if you let us program it and say add word to dictionary maybe it can learn slang?

Also maybe a version that can support Windows 7 firefox version? I've had to rip the stars away because I can no longer use it updated.

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.

хорошо помогает в копирайтинге

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.
