This (test) link generates a blank page for me via Firefox: http://demo.infysol.com/video-test.html but plays on other computers, via Firefox. Why is this happening? On my windows xp machine, I removed FF 21.0, cleared my cache, turned off my computer, reinstalled FF 21.0 and then reset Firefox, but still this link appears blank to me, but I can see it in IE8, and others on other machines, can see it via Firefox. Please help me solve this mystery.
Thanks for your reply. On that link, I don't even see a screen. But serching for "html player", I can play other players at html5 player web sites via FF. So, why not that link that everyone else can access and play?
