The amount of time I have spent trying to get firefox to accept my CA, I could've used to make my own browser.

1. Downloading the pem version with firefox is a myth. (tested with v85 & v86beta) 2. Security-enterprise-roots-enabled is a windows thing, NOT android (tested with v86beta). 3. Decoding the APK reveals that firefox does not even have this: <certificates src="user"/> 4. The builtin certificates are hardcoded into native library, and replacing one with mine does not work (suspected cert pinning) 5. The button "Accept the Risk and Continue" is the last straw it does not work.

Does firefox really support custom Root Certificates on Android? if so how?

If it works at all, it's only in Nightly. Did you read #3728?
