"Certain Firefox users may come across a message in the extensions panel indicating that their add-ons are not allowed on the site currently open. As of Firefox version
115, we have introduced a new back-end feature to only allow some
extensions monitored by Mozilla to run on specific websites for various
reasons, including security concerns."
