2028472 - Manual Sync enablement shows preselected options NOT set by Policy

Status: NEW

(Enterprise Products :: Firefox, defect)

Description

[Miruna Curtean]

Found in

151.0a1 (20260330174525)

Affected environment

Staging

Tested platforms

All platforms: macOS Tahoe 26.3, Win 11, Ubuntu 24.0

Preconditions
Admin access to stage console.
Apply policy at user level on a testable account:

{
  "Addons": false,
  "Addresses": false,
  "Bookmarks": false,
  "Enabled": false,
  "History": false,
  "Locked": false,
  "OpenTabs": false,
  "Passwords": true,
  "PaymentMethods": false,
  "Settings": true
}

Install Firefox Enterprise.

Steps to reproduce

1. Sign in with SSO on FxE with the user account where the policy has been applied.
2. In about:policies observe the sync policy shows as configured in the console.
3. In about:preferences check that Sync is OFF, but due to the Locked =false setting, it can be Turned ON.
4. Click the Turn ON Sync button and observe the pre-selected options to sync.

Expected result
Same options as the ones set through the policy should be pre-selected.

Actual result
Random options, besides the one set as True through the policy, are pre-selcted.

Note:

1. The LDAP account is also used as an FxA account on another instance of Firefox release, but I have set the same two sync options to be enabled there (passwords and settings only).
2. Tried this with both new and existing profiles and the pre-selected options are not always the same, in fact they can be rather random.

Sounds like an S2 at least.
