I’ve wanted to install an extension from outside addons.mozilla.org, but Firefox didn’t let me do it

So I’ve did a small research and looks like there are 3 ways to sideload extensions, but all of them suck

  1. Using FF Developer Edition

In the Dev Edition you can set xpinstall.signatures.required to false in about:config, but the problem is that the Dev Edition isn’t as stable as standard FF

  1. Temporarily load the extension

In about:debugging#/runtime/this-firefox you can temporarily sideload extensions, but they will be removed next time you open FF, which is annoying

  1. Modify FF code

Lastly, I found this script which modifies the FF code, but this can break things so I don’t want to use it

I’m really annoyed that Mozilla gets to decide which extensions I can install. So… what’s the best way to sideload extensions?

Edit: thanks everyone, I’m now using a FF fork (Librewolf) which lets me sideload extensions after disabling xpinstall.signatures.required

      Oh thanks, I didn’t know about unbranded builds

      Also, regular FF stores settings and profiles in ~/.mozilla/firefox, do you know where unbranded builds of FF store them?

      Edit: nvm someone else in this thread said to open about:profiles, and the path to profile folder is there

      yeah, i got a mozilla dev account and uploaded an extension for a joke, and it was pretty easy and fast.
