This does not work in the new Firefox. I won't keep my login and just shows a grayed out wifi icon and keeps saying refresh your browser. Please fix this issue.

It does not work in half the the site I use.

I really like this tool but it uses 100% of my CPU when it's on. I can toggle it on and off to see the CPU graph go from 25% to 100% over and over. It causes FF to freeze up with the little hourglass that never goes away. I have to use file manager to kill FireFox and restart since nothing works when it's frozen.

Addon can't remember login status between sessions - to repeat same login procedure to fix one-two mistakes - pretty annoying stupidity.

Crap, Rubbish, money taken for no perfomance, try replying to a post, no show. I would like my money returned.G. Henderson.

One star is only to grab attention. this is a 5 star plugin but recently since firefox quantum, the plugin is unable to correctly underline the words (misaligned underlining)

I love grammarly but unfortunately the extersion is really bad on Firefox quantum.

Doesn't work with various sites i frequent.

Doesn't work even on this review text box.

I have used it before on other browsers and think its a good tool. However I cant even get it installed at the moment. I click install, it looks like it is installing but doesn't install .

No me deja instalarlo.
Me dice que está corrupto.

I would NEVER use this extension ever again since it was the one that directly responsible for placing Opencandy on my pc. The ONLY issue I had on my pc in Years. OpenCandy is an Adware module classified as malware by many anti-virus vendors. They flag OpenCandy due to its undesirable side-effects.

This one is periodically sending "LOGS" to

f-log-extension.grammarly.io

So watch out!

Dev/s any explanation for this?

Although it was in "featured" section, but when it asks for permissions, it asks to access all my data on all website which is quite suspicious. Will it access my passwords and login details as well as bank information as well?

Spell check is highly inaccurate even allowing for differences in US & UK spelling.
Grammar check is a hoot.

Last and most critical application inserts promo codes that really dick up the results to the point I'm getting error messages for the extra codes.

The very first world it decided to spell check? [not grammar] was in English correct but in American wrong as they miss out letters all over the place. In this case changing the meaning or meaning one of two things. Making uncertainty where English had clarity. I have removed it. It lasted 3 minutes. I suspect my grammar is better than the usual user. I still know that then and than are different, quite different.

Okay if you're not good a grammar, but only really useful for Americans - can't be changed to English spelling.
