662926 - When an app tab navigates to a different origin it should lose its app tab status

Status: NEW

(Firefox :: Tabbed Browser, defect)

Description

[Brandon Sterne (:bsterne)]

I'm filing this bug as a follow-up to the Toolbarless app tab security review completed today.

When a user pins a tab as an app tab, we should guarantee that the tab always remains in the same origin (scheme, host and port) in order to keep the pinned status.  If the tab navigates to a different origin for any reason, whether user-initiated or not, the app tab should revert to a normal tab.

Actually, I believe the intended function is that they open in new tabs, which I think is a good idea. We don't want the app tab becoming unpinned unless the user explicitly chooses that option.

Yes, this sounds like bug 598587.

This bug needs to address the case where the *page navigates itself*.  An app tab can currently set its window.location via script which can easily lead to a user thinking they're on a different page.
