Suggested change

- : Minimum version of Gecko to support. If the Firefox version on which the extension is being installed or run is below this version, the extension is not installed or not run. If not provided, all versions earlier than `strict_max_version` are supported. Neither "\*" nor dot releases are valid in this field, e.g. a value of "140.0" will work while "140.1" will fail the validation on *addons.mozilla.org* with error **Unknown "strict_min_version" 140.1 for Firefox**.

For future reference:
In the past dot releases were included, as one can see at the versions listed at https://addons.mozilla.org/api/v5/applications/firefox/

These days, however, only major versions with .0 and .* are included in practice.

121.0a1 was the last version that also supported .0a1(mozilla/addons#15284).

Due to the root CA expiration in Firefox, in practice the minimum supported version capable of receiving updates is 115.0 (ESR), or if ESR versions are not included, 128.0 is the minimum supported versions. Older versions do not recognize the signatures any more, as explained at https://support.mozilla.org/en-US/kb/root-certificate-expiration
