Firefox will not play youtube videos, the video will be a black space and will not work, but IE will

I go to YouTube to play a video and it does not work, there is just a black space where the video would be, but Internet Explore will play the video, i really like FireFox, but i need for this to work and be dependable if not im gonna have to switch back to IE

i also tried this on another computer and had the same problem with Firefox

i wonder if anyone just did a windows update?

i could play it fine, in fact i was or had just used it before doing an update since it had been ages.

upon rebooting firefox no longer would play youtube videos's, explorer does it just fine so something i'm thinking in the windows update (not a firefox update) changed something disabling firefox from being able to play them.

I have the same problem. I just started today as I did not have any problems yesterday. I suspect there's something wrong with YouTube site. I have tried Chrome and IE8, same results, couldn't play the videos. Only a black screen. I have deleted cookies and cache and still won't work. I guess I'll wait for a while to see if it comes back.

ok a couple of things

try reinstalling adobe flash player i did that even though it said i had it installed and had the latest edition.

even after that they still would not play, just a black box as this post that started said(however i could play them just fine in explorer).

anyways if that don't work you can reinstall firefox and that probably will fix the problem.

i do have to add a note onto that as i didn't reinstall the latest version of firefox like i had but did the beta version, but i'm thinking the other one would work too and fix whatever setting was changed, i'm still blaming the windows update i did.

now i would go back to the other firefox if i dind't have a problem getting the beta set up the way i like it,

tabs on top, omg that was annoying, and i can't move my home button to where i want it, but thats probably due to the theme i am using.

i've gotten stuck on this theme ages ago and now anything else looks odd and i've had to over ride its compatibility since version 3 of firefox.

but i have everything the way i like except for the home button

so try reinstalling your current version of firefox, i am not sure why i didn't start with that.

ok

just reinstalled the lasted non beta and youtube is playings till just fine.

i had to check out a few things i thought i had lost in ver 4 but it appears i did nto have them in my current version either, probably due to using a theme that hasn't been supported since version 2 something.

just for those who are thinkign about upgrading to the beta a few things.

tabs by default are on top but you can change that,

if your theme is not supported and you over ride it you might have problems getting everything back to where you like it, like the home button now is default on the right side of the address bar

the top bar makes no sense, its all blank except for a ribbon line box, but you can change that to show the menu bar again, i just don't see why its like that unless its not a finished feature.

they say the drop down menu by the back button is gone but i can say i didn't have it but i don't have it in version 3.xx either probably due to the theme

but the biggest thing and this si going to keep me from going back to version 4 until its fixed is the saving and closing. there is no option to save and close in 4 only to close it.

I'm not using the beta version but 3.6.15 , but I am having this problem. I already reinstalled flash and rebooted a few times to now luck. I think it may be a problem with youtube's site.

http://www.youtube.com/swf_test.html plays the video fine with no problems, however if you click on the video to view it 'on youtube' I get the black box. http://www.youtube.com/watch?v=SHZFsJKlsuA&feature=player_embedded

Here's my latest update. I reboot my PC and now YouTube is back. I am not sure what is the problem. But I do think it's YouTube website since videos did not play with all three browsers (Firefox, Chrome and IE8). And I haven't changed anything in my PC or install any new add-ons.

If you still have the problem, try to reboot your PC to see if it works, before you reinstall Firefox. Now YouTubes videos play normally again in all three browsers.

Just found an answer that worked for me on the youtube forums, if you change the http to https it let me view videos on youtube.

Had the same problem. Adding the s to http fixed it. Now the question is why did this suddenly happen and will I have to manually adjust the URL every time?
