is it feasible to mine efficiently from a chrome or firefox plugin (with user agreement oc)? I have no idea what language and ressources are accessible to browser plugins. By efficiently I mean as good as a normal binary running directly on the machine

no, but a willing user could run a native program (like github.com/tevador/randomx-service) on their computer that a website can access with their permission

Primo uses a FF plugin to control mining from a website's instructions. Mining is done from a native miner.

I think Primo could be modified to use randomx-service, though I've not looked at the details.

cool thanks
