Why doesn't Mozilla allow me to see videos on YouTube in HD but only auto resolution?

I can see videos on YouTube only at auto resolution (usually 360p), the other resolutions do not even appear as available for me on Firefox (I do not have this issue in other browsers but I need Firefox). I have Firefox and Adobe Flash Player up to date, emptied cache and memory but the issue persists. I am using Windows XP as it is an old computer with drivers compatibility issues for newer OS's.

This problem is already known and is linked to the new HTML5 player on YouTube with Windows XP. See previous threads for more information, for example this helpful answer from jscher2000.

Thank you, I used Firefox 37 untill recently but I needed an upgrade due to another add-on. This did the trick for me (Installing those 2 add-ons I mean)
