TIL: Firefox refuses to use #DoH after the DoH server was down.
Did some maintenance on my server and killed DoH during that time. After starting it again, Firefox refused to use it, while curl already showed that it's working correctly again.
Even within #Firefox due to the configured bootstrap address I could resolve DNS correctly. Just Firefox refused to use the TRR even after making queries 🤔 I'll maybe spend some time on investigating. Restarting the browser fixes it.

@sheogorath I think there is a firefox preference to force DoH.
@blacklight447 No worries, that's what I use, guess how I noticed it's refusing to use DoH ;)
