Background:

I regularly work with old modem/router at my work sites. I usually use Firefox on PC to access the management page. Sometimes, I like to check by the sites with only my phones, to mess with the configs in the modem.

I cannot access the local IP address (https://192.168.10.1/) because of the TLS requirement is too high (SSL/TLS 1.3). I need to lower the TLS version inabout:config to 1.1. I couldn't access the about:config on Firefox Android.

I have tapped 5 times on the Firefox logo to enable to Debug page, but changing TLS requirement is NOT there.

Hi

You can find about:config in the Beta and Nightly versions of Firefox for Android available from the Google Play store.

For the desktop Firefox at least, TLS 1.0 and TLS 1.1 have been deprecated since Firefox 78 Release and should not be used now days.

I downloaded Firefox Nightly and got inside about:config and changed the value for security.tls.version.min. Thank you for all the helps.

I am using Firefox Nightly and am also unable to access about:config. How did you manage it?
