This (test) link generates a blank page for me, via Firefox:
but I can see the player and play the video via other computers, via Firefox.
Why is this happening?
I removed FF 21.0, cleared my cache, turned off my computer, reinstalled FF 21.0 and then reset Firefox, but when accessing this link (via Firefox) I see a blank page, but I can see the player and play the video via IE8. (You can probably see the player and play the video via your computer's Firefox, too).
Please help me solve this mystery.
