Attachment: Firefox Nightly issue with YouTube.doc

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/19.0 Firefox/19.0
Build ID: 20121031030750

Steps to reproduce:

I tried to view a video on YouTube on Firefox Nightly on 18/11/2012.


Actual results:

Blank video screen (see screenshot).  I checked it with multiple videos, and there was the same blank screen, i.e. not just an issue with that particular clip.

Do you watch videos through HTML5 <video>, or a Flash plug-in?

And if it's Flash, what version are you using?

My version of Flash is a beta version (11.5.502.118).  I use Windows 7 64 bit if that's any help.  Is the fact that I'm using a Beta version of Flash that Firefox has asked me to try out causing this issue?  Would I be better off with a stable version of Flash?

Youtube works fine to me with Flash 11.5.502.124 beta on Nightly 20.0a1 (2012-11-26) on Win 7 x64.
Please check if the issue occurs using Firefox in safe mode to see if your addons are causing the problem:

Or on a new, empty profile? (Don't install any addons into it)

You could also try with Flash 11.5.502.110 release http://get.adobe.com/flashplayer/

Try turning off the HTML5 player if you've opted-in and see if that helps.

It now seems to work fine without me working in Safe Mode or anything, so not sure why it didn't work before.  Temporary issue with the YouTube site possibly?
