A scene in query string url does not load on Firefox/Linux

[tallytalwar]

OS: Linux 15.10 Browser: Firefox 47.0

1. Say I am working on a scene file (scene1.yaml)....
2. I close the browser session
3. I open play again, I get last used scene (scene1.yaml) as my play session. ^^ All good here.
4. I close this play session again.
5. now you send me a link of a scene file in play (like what peter sent me above) say scene2.yaml
6. On opening the link, I still see scene1.yaml in my session instead of scene2.yaml
7. Why is it an issue for me? I am not able to see any yaml files being sent to me via mapzen.com/tangram/play link.

This is only happening with firefox and not on chrome.

What I have tried so far to test this:

1. logging in and out does not affect this behavior
2. not an issue on my chrome running on my linux
3. I see an extra circle in the name of the tab on firefox, which seemed like the scene file is PINNED. In the following screenshot, above is firefox, and below is chrome.

@tallytalwar If you open a url like https://mapzen.com/tangram/play/?scene=https%3A%2F%2Fcdn.rawgit.com%2Ftangrams%2Ftangram-sandbox%2F9c98400c05803b075fae04213d5adbb33a2e6b64%2Fstyles%2Fgrain-area.yaml#16.76675/40.76394/-73.98134 in incognito / private browsing mode, does it work? or does it load the default scene?

Firefox: It loads the default scene for me in private browsing mode. Chrome: It loads grain-area.yaml is incognito mode.
