This doesn't work but it looks great. I second CD's sentiment that the dev should be encouraged, thus this 4 star review. Especially because it seems the Chrome version is already 2.2 (see below).

UPDATE: 1 star. I have contacted the developer with no response after two months.

This would provide fucntionality sorely lacking in Firefox. It is currently absurdly clumsy to enable and disable extensions, yet there are countless use cases where I want to be able to quickly turn them on and off.

I hope we can get the update ported to Firefox!

Here is a translation from Chinese of markbinder's Jan 20, 2023 5 star review (via online translator):

"Chrome it is already version 2.2.0, I hope the author will update the version on firefox, the current version is no longer available" [guessing "no longer working" is a better translation than "available"]

Sorry, but nothing happens when i click on the extensions. No options and no information.

It doesn't work, It seems like it doesn't have proper permissions as it doesn't save groups, and literally nothing on it works = takes effect/WRITES data.

Dev needs to update and request the proper permissions for it to work.
