Original Source

Defines whether zoom changes will persist for the page's origin, or only take effect in this tab. This defaults to per-origin when {{WebExtAPIRef("tabs.zoomSettingsMode")}} is "automatic", and is always per-tab otherwise.

Type

Values of this type are strings. Possible values are:

  • "per-origin"
    • : All other tabs with the same origin as this tab will have the zoom changes applied to them. This scope is only available if {{WebExtAPIRef("tabs.zoomSettingsMode")}} is "automatic".
  • "per-tab"
    • : Zoom changes only take effect in this tab, and zoom changes in other tabs will not affect the zooming of this tab. Also:
      • in Firefox the zoom level persists across page loads and navigation within the tab.
      • in Chrome-based browsers zoom changes are reset on navigation; navigating a tab will always load pages with their per-origin zoom factors.
