This document is to clarify on the myriad of choices for loading extensions in Firefox and what will happen in Firefox 57 hits release and for each release past that (as far as we can see, things may change). There is a bug for this. This document expands it.
The main goal is prevent the running of legacy add-ons in Firefox Desktop and Android release. Update: All of the following apply to Android and Desktop.
Reference: list of add-on types
Compat. Table
This is what things will look like when Firefox 57 hits release and for each release past that (as far as we can see, things may change).
- Nightly builds are here: https://www.mozilla.org/en-US/firefox/nightly/all/
- Beta builds are here: https://www.mozilla.org/en-US/firefox/beta/all/
- Release builds are here: https://www.mozilla.org/en-US/firefox/new/
- Unbranded builds are here: https://wiki.mozilla.org/Add-ons/Extension_Signing#Latest_Builds
| Type | Status | Nightly, Unbranded Beta, Unbranded Release | Beta, Release |

Nightly leading up to Firefox 57
To assist with performance analysis leading up Firefox 57, in Nightly only we are turning off add-ons that require shims. For more information please see shims on nightly. The pref will default to false.
| Type | Status | Nightly | Beta, Release |
|---|---|---|---|
| WebExtension | YES | YES | |
| Legacy Extension (bootstrapped, overlay, XUL etc) | MPC=true | YES | YES |
| MPC=false | YES with pref | YES | |
| MPC not stated | YES with pref | YES |
An extension must pass both tests to run. Example:
- A XUL overlay extension that is signed by Mozilla and is MPC=false, *will not run* on nightly unless the user changes the pref.
- A XUL overlay extension this is signed by AMO and is MPC=true, *will run* on nightly.
- A WebExtension that is unsigned *will run* on nightly but not on release.
Prefs
To enable things on Nightly some prefs must be flipped:
- For unsigned the appropriate signing pref xpinstall.signatures.required must be flipped.
- For legacy add-ons the extensions.legacy.enabled pref must be flipped.
- For non-MPC add-ons extensions.allow-non-mpc-extensions pref must be flipped.
Notes
- AMO will stop signing legacy add-ons for version of Firefox greater than 57. Old signed add-ons will remain on servers and people's hard drives, so although AMO will stop signing them, we still need an explicit block in Firefox to prevent them loading.
- "Signed by Mozilla internally" refers to add-ons signed internally and might include Test Pilot, Shield and other add-ons.
- If we support loading unsigned temporarily, it’s assumed we load signed temporarily too.
Updates
- Removed Aurora from this chart.
- Added in the Nightly MPC=True changes.
