Adblock Plus and (a little) more

Pre-configurable preferences for system administrators on Firefox 57 and above · 2018-04-21 17:30 by Sebastian Noack

Starting with Adblock Plus 3.1 and Firefox 57, system administrators will be able to pre-configure Adblock Plus in order to suppress the first run page or to add additional default subscriptions through a managed storage manifest. This feature is now available in the developments builds as of

Suppressing the first run page was possible before as of Adblock Plus 2.6.10 through 2.9.1. However, the mechanism used there was specific to legacy Gecko extensions, and therefore is no longer supported since the migration to Web Extensions. If you used the old mechanism to suppress the first run page you should update your configuration now.

As an example, the following file, if saved to the respective location (operating system dependant), will cause the first run page to not show upon installation, and adds EasyPrivacy as a default filter subscription:

  "name": "<name>",
  "description": "Managed storage manifest for Adblock Plus",
  "type": "storage",
  "data": {
    "suppress_first_run_page": true,
    "additional_subscriptions": [

You have to substitute <name> in the manifest above and its filename with the respective ID of either the Adblock Plus release version or development builds (whichever you use):

Adblock Plus release version: {d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d}
Adblock Plus development builds:

For reference, you can also suppress the first run page (since 1.9) and add additional default subscriptions (since 1.12) in a similar way, in Adblock Plus for Chrome.
