I am trying to display a simple soft message to tell users to donate when they are using an adblocker. I do this with a script at
example.com/ads.js, simply my method is that if
ads.js is blocked then there is an adblocker (so display the message), otherwise, there is no adblocker.
I have, however, discovered that some addons like uBlock Origin block my
example.com/ads.js on Firefox, but not on Chromium-based browsers. What could be the reason for that and how can I fix it?
