User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0 Build ID: 20160303134406 Steps to reproduce: Change the window size of Firefox via the "restore / maximize" button. Actual results: If you have any Youtube Videos opened in a tab, one randomly of them will start play. Expected results: Nothing, of course. I even can't explain why changing the window size would trigger a video to playback.
As a sidenote: It does not happen all time. Maybe only 1 in 5 times.

Jim - this smells a little bit like a widget bug. Thoughts?

I tried repeatedly resizing a window (something like 6 times) with a paused youtube tab open and couldn't reproduce.

My guess is that it is racy. Tell us more about the machine you're hitting the issue on? What CPU does it have? What version of Windows? Can you also paste in the graphics section of about:support
(In reply to Loic from comment #2) > Is it reproducible with a fresh profile? I didn't have the time to test it on a fresh profile. That would be very time consuming because I don't know a single way to clearly reproduce – it just happens from time to time. Did some testing in the last 20 minutes, but not once the bug occured. :/ (In reply to Anthony Jones (:kentuckyfriedtakahe, :k17e) from comment #7) > Tell us more about the machine I'm working on a MSI Notebook from 2015, with a Intel i7-5700HQ, running Windows 10 build 10586.13.

Quadronom - are you resizing with the mouse, touchpad or touch screen? If it is a touchpad, are you using a separate button to drag or are you relying on touch drag? I'm wondering whether we're delivering touch events to the window. Brian - you know something about events? Any ideas?

(In reply to Anthony Jones (:kentuckyfriedtakahe, :k17e) from comment #9) > Quadronom - are you resizing with the mouse, touchpad or touch screen? Actually I never resize my firefox at all, it's always maximized (But if I would, I'll use my mouse). I experienced the bug when I accidentelly missed the minimize button and hit restore. I might want to add, that this could be a weird youtube bug as well – I didn't have the problem for a few days now…

Guys, it got even weirder. In one tab I had Amazon Prime Video (Silverlight!) open, then I plugged an external monitor into my notebook: and tada, suddenly the playback of my Dexter episode started!

We were not able to reproduce this. Perhaps more details for STR could help. I'm close this as INCOMPLETE. Feel free to reopen if you have more information that helps us proceed, appreciated.
