User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:46.0) Gecko/20100101 Firefox/46.0 Build ID: 20160103030302 Steps to reproduce: I've been looking at ways to simplify building UI for push and one of the things I noticed was that calling subscribe and simply closing the permission dialog results in the subscribe() promise not resolving. Steps to reproduce: 1. Go to: https://simple-push-demo.appspot.com/ 2. *Double check current permission state is to always ask 3. Click the toggle switch 4. Close the permission dialog (i.e. click the cross in the top right of the permission pop up) Actual results: The UI stays disabled. Expected results: The UI should either switch back to the off, enabled state, or switch on to the enabled state.

Thank you for triaging this! I think this is "working as intended" (see bug 675533 for the same discussion around geolocation prompts). A lot of comments on that bug express confusion and frustration around the current behavior, so maybe it's time to revisit. FWIW, if you dismiss the dialog without granting or rejecting the permission, the icon remains in the address bar, and you can recall the dialog by clicking on the icon. In practice, I'm not sure how many folks do that, or are even aware of it.

I hadn't noticed the UI in the url bar. I suppose this is a FF feature. My assumption (perhaps wrongly) was that a permission status would be prompt, granted or denied after a User Agent had hidden it's permission. This introduces a kind of limbo state of a "pending-response" which could lead to some odd UX within websites, but I can see how this could be desirable from a UA and user. Thanks for the info.

Continuing the discussion in bug 1241749.
