How to enable add-ons in Tor Browser for Android

I'm sick of this idiocy in what is now a crippled browser. Tor Desktop and Orfox have add-ons enabled by default, but not Tor Browser for Android. To make matter worse we're not told HOW to enable them: "We know what's best for you - and we've thrown the key to unlocking our crippled browser down the well aka about:config."

Firstly, what is the specific !about:config configuration to enable add-ons that shouldn't be disabled in the first place? Secondly, why are you so determined to cause annoyance, irritation, and a waste of time and effort on the user's part, trying to get an answer to something that shouldn't even be an issue?
