Version
109.0 of the Firefox browser has been released. The headline feature
this time is the enabling of Manifest
Version 3 support — a new extension mechanism that, among other
things, gives a higher degree of control over what extensions can do.

MV3 also ushers an exciting user interface change in the form of
the new extensions button (already available on Firefox
Nightly). This will give users direct control over which extensions
can access specific web sites.
Users are able to review, grant, or revoke MV3 extension access to
any website.
