Thanks, but this doesn't appear to offer equivalent features. RefControl allowed a default action overlaid by siste (pattern) specific overrides.

One could block refer(r)er altogether, and then adjust on a site/resource basis as needed.

There is one current web extension compatible extension that purports to do this, but when I tried it, it didn't want to cooperate with my configuration, despite adjustments. Further, it sucked Discus comments into its local configuration dialog/page, something that I find... sucks.

Finally, it wasn't open-source and didn't have a well-known provinance. All this didn't leave me feeling too confident in it.

P.S. uMatrix is supposed to provide layers of referrer control, but I haven't made the effort yet to switch over to it including switching some of my other points of configuration to use it instead.
