Please see the recorded video for this issue: https://drive.google.com/file/d/0B_L6mNdlzO5TU0VidmhsMUpGRU0/view. Also I'm not sure if it's ok to be able to clear the "persistent storage" permission from a private window("Control Center" or "Preferences") since from a private window sites cannot be persisted. Please confirm the expected behavior.

The video from comment 1 is not ok. Please try this one: https://drive.google.com/file/d/0B_L6mNdlzO5TMUQ1UTBJUVNGZE0/view

Franics, This bug we've discussed in all hands meetings with Roxana and you. We need UX to comment the preferred behavior for "Case 2". Right now, removing persistent permission using permission manager won't also remove persisted storage. Permission manager doesn't know anything about persisted storage, it only handles permission. For case 1, as we all agree that in the storage meeting previously, in bug 1348223 we have conclusion: "Currently we expose site data under permissions (the persistent storage permission), but this does not make much sense, as clearing the permission doesn't actually change the abilities of the site in question. It will still have persistent data and the data won't be gone. So instead we should not expose site data under permissions, but have it under security where we also place cookies. We just need one option there: Site Data [Remove] (This same criticism applies to the "Show site information" dialog. Ideally we fix both at the same time.)" For case 2, can UX clarify the UX specification for private browsing window?

hi Mark, could you please comment on the case 2 mentioned in the comment3 ? thank you very much

Please confirm the expected > behavior. You can't persist in private browsing window. We fallback persist() to persisted() in private window because persist in private browsing window doesn't make sense from the privacy point of view.

This will explicitly clear both permission and storage space.

hi Mark, could you please comment on this? thank you very much

(In reply to Francis Lee [:frlee] from comment #7) > hi Mark, > > could you please comment on this? > > thank you very much For case 2, I'd say ideally a website's permission status in each private browsing session is isolated and is inherited from the normal browsing session. That means, clearing a website's permission in private window X won't affect the permission status in private window Y and all the other normal windows.

NI myself, we will triage this in the Storage project meeting.

[Triage] Case I is a known issue tracked in bug 1348223, that is put in our backlog (P3). Case II - per UX comment in comment 10, the actual behaviour SV reported is as our UX expected. So this part is invalid. Let's use bug 1348223 track case I, and I am going to close this as invalid to reflect case II. Thanks.
