Do extension pages share database allocation with the background page?

Do extension pages have their own indexedDB databases apart from that of the background page, or does the moz extension address share an origin and single database allocation?

According to the MDN document on extension pages,

These pages also get access to the same privileged JavaScript APIs that are available to your extension’s background scripts. However, they are in their own tab, with their own JavaScript event queue, their own globals, etc.

I’m going to test it out, of course, but thought it couldn’t hurt to ask those who know to confirm what I see.

Thank you.

Extension pages are in the same origin as the background page.
