amazing and fantastic extension. for those who find it not working properly: once you're on the website you want to unlock cors for, CLICK THE EXTENSION ICON in the list, so the letter "C" on it's icon BECOMES YELLOW. that means you turned it on: works AMAZINGLY, best extension ever.

doesn't work, doesn't do anything, all CORS requests still fail for all websites regardless of any settings toggled.

Un desastre...no funciona...como si no existiera..

Does what it says on the tin, would be nice though to have the ability to whitelist sites, like just localhost, instead of all domains.

Great that you can modify "Access-Control-Expose-Headers", too! Very useful.

Does not work as of September 2023.

With this addon youtube playback can't start since June 2023

I doesn't work

don't work

It's working good. But some sites work incorrect when extension enabled. Whitelist option will be good

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!
