Woah! Finally cors extension that works!! Thank you so much mate. This is a much needed one on firefox, specially for a frontend developer. I felt hopeless, I was about to make my own but this saved a lot of time and effort! Deserves 5 shining stars!

It's promising add-on but it does not work in Firefox 86. I used the COR tests and it fails all except redirect

Work as expected. Just click on icon to enable/disabled it

Does not work for Firefox Developer 78 and Firefox 77

Does not work on FF 74.

Thats works! Thx!

This works well on my firefox ver 72.02 (mac) while other add ons do not work anymore.
