Build ID: 20151019004047

Steps to reproduce:

enter: http://www.movie-box.pl/204/Wikingowie.html

Actual results:

When using Fiferox Developer Edition 64 bit I have found out that flash videos are not working - there is just empty black box without flash menus when you right click on it. On 32 bit version it works fine.

I use FF DE 43.0a2 (2015-10-19) 64 bit on Windows 7 64 bit with Flash

I tried with empty profile - does not help - so it is not a problem with add-ons.

Expected results:

Flash video should play fine.

This works for me with the Aurora 43.0a2 20151019004047 64 bit on Windows 8.1. The two ads before the clip have to be completely loaded before they play. Please check in the location bar on the left that the Flash plugin is enabled.

I already tried all possible solutions - nothing helps.

I know that some people have this problem and some don't.

I observe this issue in my home PC, while on PC in my work Flash plays fine.

The same issue is observed in Cyberfox: https://8pecxstudios.com/Forums/viewtopic.php?f=5&t=1191

Is there a way to debug the problem?

There was a previous bug (see bug 1201438), but it has been fixed.

But previous bug says that there was a sound and no vision. In my case there's no sound and no vision - like Flash plugin is not started at all.

I have the same bug on 64bit Firefox 42 & 43b, flash 19, windows 10.
But not on all videos, for example flash youtube videos play fine, while dailymotion or rutube videos doesn't even start.
If anyone still experiencing issues: please update platform and Firefox version.
Working as expected I checked on Windows 10 and Windows 7 64-bit
Please need info me if there are other concerns. Thanks.

Resolving as incomplete due to lack of response. I have also retested 64-bit Firefox on Release and Aurora with current Flash - no errors.
