This young extension is an open and secure alternative to proprietary solutions such as Grammarly.

Main Feature: unlike competitors, it does not send anything to remote server unless user explicitly asks it to do so.
Ability to opt-in for automatic checks ONLY for specific websites is a very useful feature and a good design.

Keep up great work!

Great tool for those who want to write the correct way.

And better yet, is open source.

Ugly icon tho.

Great news!!! But somehow it is labeled as "Legacy" in my Add-ons list.

This seems to be a Firefox bug. It's not tagged "legacy" for me and it also works with FF beta (which is FF57).

Nice, free, and very useful for non-native english people.
