I just got the latest "Firefox Daylight" update on Android. This is version 79.0.5 (Build #2015758619) on Android 10.

If I try to access about:config, I get redirected to resource://android/assets/low_and_medium_risk_error_pages.html?&title=Cannot+Complete+Request&button=Try+Again&description=%3Cp%3EAdditional+information+about+this+problem+or+error+is+currently+unavailable.%3C%2Fp%3E&image=&showSSL=false&badCertAdvanced=Advanced%E2%80%A6&badCertTechInfo=%3Clabel%3ESomeone+could+be+trying+to+impersonate+the+site+and+you+should+not+continue.%3C%2Flabel%3E+%3Cbr%3E%3Cbr%3E+%3Clabel%3EWebsites+prove+their+identity+via+certificates.+Firefox+does+not+trust+%3Cb%3Eabout%3Aconfig%3C%2Fb%3E+because+its+certificate+issuer+is+unknown%2C+the+certificate+is+self-signed%2C+or+the+server+is+not+sending+the+correct+intermediate+certificates.%3C%2Flabel%3E&badCertGoBack=Go+Back+%28Recommended%29&badCertAcceptTemporary=Accept+the+Risk+and+Continue

This page just shows Cannot Complete Request Additional information about this problem or error is currently unavailable.

I have uBlock Origin installed, but I can't see how that would block about:config. I see some SSL error text in that big URL blob, not sure what that's about.

That's correct. It is not available in the stable version.

You can download both Firefox for Android Beta and Firefox Nightly from the Google Play Store.

Is it not available in the stable release versions of Firefox for Android? I am not using a "beta" version. I realized now that this question was posted in the "beta" section. I just clicked the "support" button in the app and posted this question.
