748222 - Add support for a back button to allow a user to go back to the last page he/she visited

Status: RESOLVED WONTFIX

(Firefox Graveyard :: Web Apps, enhancement)

Description

[Jason Smith [:jsmith]]

Allow a user to have the ability to select to go back to the last page he/she visited while executing the application. This means:

1. Go to page 1
2. Go to page 2
3. Select back button

Result: User is on page 1.

Note - The android implementation for the web runtime will have this ability since android has this built-in. We should equivalently support it in the desktop implementation for consistency.

Android provides a back button whose behavior is defined by the app.  It won't necessarily mean "go back one page" for webapps on Android, and it probably shouldn't, given that it doesn't mean that for native apps.  So we shouldn't implement such a button for desktop, even if we wanted to be consistent with Android in this respect (which is also unclear, given that desktop has no equivalent affordance).

Fyi, app developers can check window.toolbar.visible to decide if they should add their own navigation UI.
