Your screenshot doesn't show just /any video/ but a YouTube video. These don't play through Firefox's built-in player, but YouTube's own complex HTML5 player.

It works for me in Linux Mint KDE 17.1:
* Cursor over the volume icon shows the tooltip “Mute”.
* Cursor over the volume bar changes its colors a bit to highlight it.
* Cursor over the seek bar shows the time and a thumbnail.
* Cursor over the video shows nothing special.

Please update your Firefox Developer Edition build, then test in a brand new profile.

The bug apparently it's resolved on Nightly version (40.0a1). 


Curious note
   The bug appears when the page size is > 70, others sizes show normal indicators

The graphics information in the comment #3. 

Still presents the bug on the version 38.0 stable and Developer edition. 

Very curious situation, with the theme FT DeepDark 12.0.1 disappears the bug. Appears only with default theme is active. I try it with other complete theme and the bug is still.

I want to comment on this problem. I'm having the same problem with Firefox, it happened to me when I updated to version 37. Happens on several Linux distro's. At the time when I typing this I using Firefox 38 on Ubuntu 14.04 and I still have the issue. Starting Firefox in safe mode without all add-ons or tweaks didn't fix the problem neither using a new profile. It happens on multiple systems, one has a Intel GPU, the other has a Nvidia GPU with the Nvidia drivers installed.

This problem seems to have something to do with HTML5 because this problem only occurs when I use the HTML5 player on YouTube. On the Flash player it doesn't happens. I have created a screen-cast of the problem. At the time I recorded this I was using Kubuntu 14.04.

I am not able to reproduce the problem on my end, unfortunately. I tried with nightly and an older version (38) as well.
