Hi,

Thank you for taking the time to report this issue. However, I was not able to reproduce the issue following the steps provided on Windows 10 or Windows 7, on any of the 62 Release Build, 63.0b4 Developer Edition Build or 64.0a1 Nightly Build. 

Could you please retest this using latest FF release and latest Nightly build (https://nightly.mozilla.org/) and report back the results? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E). If the issue is still reproducible, could you please provide us with some more specific examples so we can try to recreate it with the same set-up.

I can confirm this issue is reproducible on 60.2.1ESR and 63.0b7 on Windows 10 x64 with link: https://www.twitch.tv/, when you hit the space bar the video not paused, but exit from full screen mode.

I was trying some site using default controls and no extra event listeners, 
https://www.w3schools.com/html/html5_video.asp and I didn't get that behavior.

Yeah, confirmed that this reproduces on Windows (but not OSX). Chrome on Windows pauses, as I would expect. 

Dennis, can you take a look?

STR:

1. go to https://www.twitch.tv/
2. fullscreen any video, and press play
3. press spacebar

expected:
video pauses

actual: 
fullscreen exits

This actually does not appear to be a webcompat issue after all. The same behavior can be observed in other video players, even the native video controls. After some head-scratching, I realized that there is an inconsistency between the platforms in terms of where the focus ends up when clicking the fullscreen button. On macOS, the focus goes over to the <video>, on Windows, it stays on the fullscreen button.

I filed bug 1502093 for that, and since there is likely nothing twitch should do to workaround that, I'm closing this as a dupe. If it turns out to require a twitch workaround, we can reopen.
