Fórum podpory Firefox pre Android

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.

Question: Where is the setting for security.tls.version.min in Firefox Android 120.0?

REF: Firefox v109.2.0 / Windows 7 x64

How do we get Firefox to load the browser tabs, which are activated from other Android applications, diverted in the background?

The now, inaccesible, "about:config" switch" for this action is/was: "browser.tabs.loadDivertedInBackground". The incessant switching between browser and active app can be most unproductive and unpleasant.

About:config simply shows me a blank screen.

I need to customize a few settings and I presently cannot. This question marks this as answered but the answer is talking about a solution to the specific reason they were trying to access about:config, not why they cannot access it. https://support.mozilla.org/en-US/questions/1373286

Others say to use the nightly build, which I don't want. https://support.mozilla.org/en-US/questions/1302626

What's the deal? I've spent an hour or so now looking this up and haven't found anything.
