To replicate the bug:
Open a private window using command/ctrl+shift+p
Go to https://hacks.mozilla.org/2010/01/offline-web-applications/
Click on the todo demo link (shortened) http://is.gd/RNGOU6
When prompted, allow the site to store data for offline use.
Try adding a task
Close the Private window
Go to the advanced tab in preferences window and select the network section
https://developer.mozilla.org still shows in the preferences.
I would expect it not to show up - this seems to me like a leak between private and non-private browsing.

Yeah, we don't block offline cache in PB mode.
Summary: Offline data storage network preferences from private tabs are stored even after private browsing closed → Do not store offline cache data in private mode

I need to verify this, but I believe we don't actually store any data in private windows, but we do store the permission for the site to store data.

We also need to change the user prompt to something sensible.
Try the following to reproduce this:
1. Make sure no offline data is stored for a website
2. Open a private window
3. Visit that site and click "Allow"
4. Site itself will behave as if there was no offline data
5. Actually go offline
6. No visit the site in a non-private window
7. Site will show the content stored in the offline cache
Thus, it appears that indeed the data is stored but not used by a private window.
(tested with Firefox 21.0 and the http://html5demos.com/offlineapp site.)

If so, this is a dupe of bug 819496.
