Defines whether zoom changes will persist for the page's origin, or only take effect in this tab. This defaults to per-origin when 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
tabs.zoomSettingsModeis "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,
per-tabzoom changes are reset on navigation; navigating a tab will always load pages with theirper-originzoom factors.
