I merged your changes into my branch the other day, and then merged into main tonight. Thank you very much. The solution without looping is a huge improvement!

By the way, I actually wanted to write yesterday that the idea of the MutationOberserver was very brilliant!

I wish I could take credit, but it came from one of the AIs. Claude, I think, but maybe ChatGPT. I didn't even know that mutation observers existed before that. My part was just stumbling into the right question. ;-)

The host_permissions should ensure that the fetching of data from these sources is permitted.

Yeah, that's how I understood it, but my browser doesn't seem to care whether those settings are actually there or not. I left them in, and added justyy's load balancer, too - just in case we want to use them later. I'm still not clear on why it doesn't really seem to be needed in Brave, though.
