How to Bypass Firefox's Add-on Signing Check

Pre FX 55               FX 55 and Up

These bypasses will probably die when FX 57 is released.

 

These bypasses do not apply to FX 52esr versions.
FX 52esr honors the xpinstall.signatures.required - false
about:config setting.

 

For Firefox versions before v55:

1. Download the two configuration files here.

2. Copy the two files into the Firefox program directory.

For Windows OS:

The paths below are for a 32 bit OS with 32 bit Firefox
and for a 64 bit OS with a 64 bit Firefox.

Copy config.js to:

C:\Program Files\Mozilla Firefox\config.js

Copy config-prefs.js to:

C:\Program Files\Mozilla Firefox\defaults\pref\config-prefs.js

and

$ sudo cp autoconfig.js /usr/lib/firefox/defaults/pref

 

If you run into difficulty installing an add-on and get this warning:

You will need to temporarily remove the config-prefs.js or autoconfig.js files to be able to install some add-ons (remove them with FX closed). Once the add-on is installed, put the file back to continue using the add-ons.

   If your unsigned add-ons, that you have installed, still show as not verified, delete the following files from your Firefox profile (they will be rebuilt when Firefox is re-opened):

addons.json

addonStartup.json.lz4

compatibility.ini

extensions.ini

extensions.json

 Note: If you delete these files, when you re-open Firefox, all of your add-ons will need to be re-enabled (not re-installed). If the unsigned add-ons still show as not verified, reinstall the unsigned add-ons.

Note: When updating Firefox, you need to make sure
these "inserted" files are still there.
