There should be a way to allow extensions to execute only on specific websites like the Site access option in Edge does, this improves extensions usability and may also enhance privacy.
Hello, and thanks for continuing to engage engage with this topic. We have assigned an engineer to work on this, and development began last week. You can follow along on the progress on this BugZilla ticket if you wish. I don't know the launch date yet, but I will post an update in here when we have more clarity.
I appreciate your patience on this, we have a development team of 3 people in Firefox extensions, and lots of competeing priorities so it's hard to get everything shipped as quickly as we'd like to. As this feature involves changes deep in the foundations of the extension code we need to make sure we do it right and test it thoroughly or it could break extensions for a lot of people.
