Verified with Mozilla Firefox v8.2 — updated on September 2, 2026
Supported on: Firefox 155 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Mozilla\Firefox User Configuration\Administrative Templates\Mozilla\Firefox Description
If this policy is enabled, Firefox does not launch automatically when the user logs in. Any existing launch-on-login entry is removed and the "Open Firefox automatically when your computer starts up" checkbox in Settings > General > Startup is hidden. If this policy is disabled or not configured, the user controls whether Firefox launches on login.

Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
