Incompatible with Firefox's privacy tools (in order to use it, they tell you to disable some of them: https://support.grammarly.com/hc/en-us/articles/115000090451-Error-Grammarly-is-active-but-key-features-are-missing)

Working fine until latest Firefox upgrade. Not actively monitored by Mozilla may be the cause.

I would give this more if they had an affordable tier for premium. As a developer I understand the yearly subscription model, but, with everyone using it 144$ is too steep a price. Half that I would maybe pay, but this is way too much.

THIS IS A FANTASTIC I'M LOVING IT:)

Overall an excellent extension. My only gripe is the release notes are never updated when a new version is released.

Can't even log into my account

It sends EVERYTHING you type back to their server and when I mark a suggestion wrong, the EXACT same suggestion comes up. Also, it doesn't get everything Google does.
