Upgrading the Local Reset Extension
The Local Rest Extension (LRE) cannot be upgraded in place. Older versions must be uninstalled on workstations before the new 12.5 interceptors are installed. This can be done in workstation batches and does not need to be done simultaneously.
When users cannot install extensions on their web browsers, an organization's administrators would need to force-install the extension for their users.
Google has some documentation on how to do this for Chrome:
For Firefox documentation, see:

A GPO would then be used to install the native .msi extension on the workstations. This is the generic upgrade approach.
