firefox_disable_autoupdate.md

Firefox is no longer supporting disabling the auto update feature via about:config. Previously there was a setting app-update.enabled which could be set via a vendor.js file.

This was moved to the policy engine in Bug 1420514.

Since I'm managing Firefox Nightly with my package manager I wanted to disable auto update again.

In order to do this simply create a directory called distribution in within you Firefox installation directory. Then create a file named policies.json with the following content:

{
 "policies": {
   "DisableAppUpdate": true
 }
}

in that directory.
