Created attachment 8902462 [details] FF-info.json User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:57.0) Gecko/20100101 Firefox/57.0 Build ID: 20170829100404 Steps to reproduce: 1. Use Firefox Nightly with a bunch of opened tabs. 2. Switch to / login as another operating system user without logging off. 3. switch back users and try to interact with Firefox Actual results: Content is not responding to clicks. Switching tabs is also not possible. Quitting Firefox, reopening it and restoring the session makes it work again. Expected results: It should be interactive, just like before switching users.

I tried to reproduce it step-by-step, but it worked this time. Some time later I had the problem again. Maybe it is caused by a specific action done by the second OS-user. Anyways, if I find out more accurate steps to reproduce it reliably, I'll post them here. thanks
