Path in the GPO console
Computer Configuration\Administrative Templates\Mozilla\Firefox User Configuration\Administrative Templates\Mozilla\Firefox Description
If this policy is enabled, you can specify a Firefox version as xx. or xx.xx. and Firefox will not be updated beyond that major or minor version. If this policy is disabled or not configured, Firefox will update normally.

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.
