Hi Q,

I followed the instructions described in the google groups link and I wasn't able to make unsigned extension to work on the latest Firefox release, neither on Ubuntu or on Windows 10. For me, the extension that I am trying to install is blocked, as expected.

Are you able to install unsigned extensions on the latest Firefox release? If yes, could you please detail how you managed to do this?

I reported it based on posts in other threads which said it does work;  I haven't tried it myself yet.  I'll be happy to try, but I need a pointer to an unsigned add-on to test with.

Attached file popup.xpi
I've attached an unsigned addon, make sure to delete it after you're done :)

Thanks.  I'm running a Gentoo build of Firefox 51.0.  I think the post at Google has syntax errors, but with the following two files in place, I was able to install the unsigned popup.xpi.  

$ cat /usr/lib64/firefox/config.js
try {
  Components.utils.import("resource://gre/modules/addons/XPIProvider.jsm", {})
catch(ex) {}

$ cat /usr/lib64/firefox/defaults/pref/local-prefs.js
pref("general.config.obscure_value", 0);
pref("general.config.filename", "config.js");
After untarring the Mozilla-supplied Firefox 51.0.1 in my home directory, I created ~/firefox/config.js and ~/firefox/defaults/pref/local-prefs.js with the same content as in comment 4, and was able to install popup.xpi.

In case it matters, the command I used to launch the Mozilla-supplied Firefox was 

$ ~/firefox/firefox -CreateProfile testingprofile && ~/firefox/firefox -P testingprofile

(to create a new profile named "testingprofile" then launch Firefox with that profile).

Thanks Q for all the help.

I was able to reproduce the issue on the latest Firefox release (51.0.1).
