The motivation for the author of the webextension is good, but... it did not protect the browser user from the fact that ANY tracking company can easily deteсt that you are using the extension to bypass the reading of your real data. So you are already trying to hide from them and this is a huge fingerprint. Webextension code needs to be rewritten significantly in order to protect it from detection. Good luck to the author, but in this form, the extension only pays attention to tracking companies.
