1/2 Add-on was removed by #Mozilla from store
Current installations (by custom collection in #Firefox Beta/Nightly or Firefox-clone) will stay active, but with no more updates
There is still an elaborate workaround for regular Firefox though
install an old version of Firefox (like v68.11.0 https://www.apkmirror.com/apk/mozilla/firefox/firefox-68-11-0-release/)
you have to remove your current Firefox app (or use an old Firefox Beta version)
download add-on's xpi-file (custom version if you want to use custom sites) from releases
https://gitlab.com/magnolia1234/bypass-paywalls-firefox-clean/-/releases
and install/open in Firefox
now you can update Firefox to the latest version
add-on will stay active & automatically updates to the latest version
in add-ons it will be labeled as not yet available and also has no more option to enable the add-on in private browsing
