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. 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.

What is this bullshit? Feel like this will lead to adblocks being blocked for certain websites under the guise of "security", aka: we don't have to justify shit to you.
