browser_specific_settings
key contains keys that are specific to a particular host application.
Firefox stores its browser specific settings in the
gecko
subkey, which has the following properties:
id
Is the extension ID. Optional since Firefox 48, where the extension ID is derived from the extension's signature. Mandatory if the extension is unsigned (and not loaded via
about:debugging
)。见
Extensions and the Add-on ID
to see when you need to specify an add-on ID.
strict_min_version
Minimum version of Gecko to support. Versions containing a "*" are not valid in this field. Defaults to "42a1".
strict_max_version
Maximum version of Gecko to support. If the Firefox version on which the extension is being installed or run is above this version, then the extension will be disabled, or not permitted to be installed. Defaults to "*", which disables checking for a maximum version.
update_url
Is a link to an extension update manifest . Note that the link must begin with "https". This key is for managing extension updates yourself (i.e. not through AMO).
See the list of valid Gecko versions .
The extension ID must be one of the following:
extensionname@example.org
The latter format is easier to generate and manipulate. Be aware that using a real email address here may attract spam.
例如：
"id": "extensionname@example.org"
"id": "{daf44bf7-a45e-4450-979c-91cf07434c3d}"
警告： Adding Edge-specific properties to the manifest caused an error prior to Firefox 69 which can prevent the extension from installing.
Microsoft Edge stores its browser specific settings in the
edge
subkey, which has the following properties:
browser_action_next_to_addressbar
Boolean property which controls the placement of the browser action .
true
is equivalent to setting
browser_action.default_area
to
navbar
.
false
is equivalent to setting
browser_action.default_area
to
menupanel
.
警告： Adding Safari-specific properties to the manifest caused an error prior to Firefox 69 which can prevent the extension from installing.
Safari stores its browser specific settings in the
safari
subkey, which has the following properties:
strict_min_version
Minimum version of Safari to support.
strict_max_version
Maximum version of Safari to support.
Example with all possible keys. Note that most extensions will omit
strict_max_version
and
update_url
.
