1477615 - "autoplay-media" permission grants don't propagate across tabs in Private Browsing mode in the same session

Status: RESOLVED DUPLICATE of bug 1478869

(Firefox :: Site Identity, defect, P2)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

STR:
1. Open a Private Browsing mode window.
2. Open YouTube.com
3. CTRL+Click on a video on the YouTube speed dial.
4. Switch to the newly opened tab.
5. Opt to allow autoplay on that tab, video should start playing.
6. Close tab, returning focus to the YouTube.com home page.
7. CTRL+Click on another video on the YouTube speed dial.
8. Switch to the newly opened tab.

Observed result:
* Autoplay permission dialog pops up, asking for permission to autoplay.

Expected result:
* YouTube has already been granted permission to autoplay in this PB session, so we should remember the permission until PB mode is exited.

Note, users could grant an allow permission to YouTube.com in non PB mode in order to get the behaviour they want, but there are likely other sites that are frequently used in PB mode for which users don't want to store a permanent permission to autoplay. Like the shopping channel's video stream for engagement rings for example.

Shouldn't this be "Importance: blocker"? ;D
