action.setTitle()
Sets the browser action's title. The title is displayed in a tooltip over the browser action's icon. You can pass a tabId
in or a windowId
as an optional parameter — if you do this then the title is changed only for the specified tab or window. Tabs or windows without a specific title inherit the global title text, which defaults to the default_title
or name
specified in the manifest.
Note: This API is available in Manifest V3 or higher.
