AppUpdatePin

Prevent Firefox from being updated beyond the specified pinned version.

The format for versioning is semver, which uses MAJOR.MINOR.PATCH format.

You can specify the major version as xx. (e.g, 140.) and Firefox will be updated with all minor versions, but will not be updated beyond the major version.

You can specify a major and minor version as xx.xx (e.g, 140.0) and Firefox will be updated with all patch versions (140.0.1, 140.0.2), but will not be updated beyond the minor version.

You should specify a version that exists or is guaranteed to exist. If you specify a version that doesn't exist, Firefox will update beyond that version.
