I can confirm that the problem is reproduced on Win10 Nightly62.0a1 and Firefox60, but not on ESR52. Error in Browser Console(Firefox60): NS_ERROR_NOT_AVAILABLE: videocontrols.xml:391 Request for fullscreen was denied because requesting element is not in the currently focused tab. foobar.mp4

The error message shown in console is FullscreenDeniedNotFocusedTab, which means it fails IsInActiveTab check[1], so the reason is somehow we don't set active state to either the docshell or the window. Switching tab / window or even just changing focus to other chrome element seems to help this.

(In reply to Xidorn Quan [:xidorn] UTC+10 from comment #3) So likely the same root cause as bug 1459327 and bug 1467206.

Edge case, so dropping this from weekly triage. We could still take a patch for 63 or even 62.

Happy to take a patch in nightly; if it seems low risk enough please feel free to request uplift to 65 beta.
