Tor Browser does nothing when clicking "Allow" for offline storage use
I wanted to checkout a "secure webmail app" that a friend was talking about. When navigating to https://mail.whiteout.io/ in Tor Browser 4.0, however, I cannot click the "Allow" button.
Preferences > Advanced > Offline Web Content and User Data > Tell me when a website asks to store data for offline use checkbox is checked. However that setting only toggles the
browser.offline-apps.notify pref. I think what we want is
browser.cache.offline.enable=true, but we'd likely need to audit those APIs to ensure they do not do anything potentially unsafe.
