tabs.ZoomSettingsScope

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.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, per-tab zoom changes are reset on navigation; navigating a tab will always load pages with their per-origin zoom factors.
