> I should be able to without interference from my web browser

You should be. From what I can remember, both Firefox and Chrome add exceptions to user installed certificates that disable requirements such as certificate transparency logs and even things like HPKP back when that was a thing.

It's easy to make a mistake and install certificates in the system chain instead (especially on Windows), but if you pick the right certificate store I don't think you should be having any trouble. That said, it's been a while since I last dealt with Chrome, maybe things have gotten worse.
