Hello forum, I have a noob question:
There is this basic error coming up with all basic extensions I’m testing:
My Extensions "Can’t read and edit Data on this website"
Even this basic tutorial doesn’t work: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Your_first_WebExtension
I reainstalled Firefox and also deleted all the settings files. Still.
What could it be?
Thanks so much, Kakaoboy
