Support per tab page zoom (as opposed to per-origin or global)
As per bug 1319387 it would be nice if we could support a zoom level per tab. It looks like the current options are global or per origin. If that was added, then we could provide a WebExtensions API for it. Not sure where the right component for this bug is, please move if not appropriate.
Component: Disability Access → Panning and Zooming
Product: Firefox → Core
Summary: Support per tab zoom → Support per tab page zoom (as opposed to per-origin or global)
Page zoom is handled by layout, not APZ.
Component: Panning and Zooming → Layout
Hmm, as far back as I can remember, if browser.zoom.siteSpecific is set to false, zoom reverts to "per tab" in the following sense: once the user changes the zoom level from the default for a particular web page, all pages subsequently loaded in that tab keep the same altered zoom level, regardless of site. Interestingly, if you duplicate the tab by Ctrl+dragging the tab to a new spot on the Tab bar, this particular bit of context is not copied over to the new tab.
