Defines whether zoom changes will persist for the page's origin, or only take effect in this tab; defaults to per-origin when in automatic mode, and per-tab otherwise.
Type
Values of this type are strings. Possible values are:
per-origin |
Zoom changes will persist in the zoomed page's origin, i.e. all other tabs navigated to that same origin will be zoomed as well. Moreover, per-origin zoom changes are saved with the origin, meaning that when navigating to other pages in the same origin, they will all be zoomed to the same zoom factor. The per-origin scope is only available in the automatic mode. |
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. |
