How do I allow this site to set the 'user' cookie, but not the '_cfuid' one? Since Cloudflare is proxying, both cookies are first-party.

FF61 on Mac. Solutions for Chrome would also be interesting.

Note that I specifically don't want 'self destructing cookies' or session- or time-limited ones. I just want to white/blacklist by site, cookie name, and perhaps cookie content.

I've briefly looked for suitable extensions, but not yet found anything.
