Firefox shows a black box when viewing YouTube videos, though Chrome doesn't.
So I tried to watch a video on YouTube, yet Firefox just shows a black box. Neither the video nor the audio will play. It doesn't crash my browser or bring up any errors, which leads me to believe that it is not a Flash Player problem.
I opened Google Chrome and tried, and it plays YouTube videos with no problems.
I restarted my computer, yet it still does not work.
Any assistance is very much so appreciated.

I just noticed that I can view embedded youtube videos linked from other websites but I cannot view the same videos directly at youtube.com

Yeah, I can do the same, qazwsxedc.
Does it help if you change the http link to https?
Clear the cache and the cookies from sites that cause problems.
- "Clear the Cache": Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"
- "Remove the Cookies" from sites causing problems: Tools > Options > Privacy > Cookies: "Show Cookies"
Changing to https fixed it for me. After adding the 'S' it remained for any other video I played.

https works perfectly. But the average Firefox or YouTube user probably won't know this. Hope a real fix is in the works.
I am having the same problem - and the https thing is working for me. Annoying as hell though.

I use Windows 7 and I have a solution. I had this problem as well where no videos would play and the thumbnails weren't visible either.
My solution: I fixed it by disabling Flash from the add-ons menu and I also reset the preferences by going through the default pathway: C:\Users\Owner(or whatever your username is)\AppData\Roaming\Mozilla\Firefox\Profiles\xxxxxxxx.default.
I also disabled hardware acceleration by going to a random video that used flash (I went to a game that plays an advertisement before loading and right clicked it, clicked settings..., and then went to the display settings [first icon on the bottom], and unchecked the hardware acceleration box).
After doing all of this, everything was fine. I was able to play an entire video with nothing messing up and was very happy so hopefully this helps!
I use Windows Vista, Mozilla Fire Fox 8.0 this problem has been very annoying to me . . . but I did the following: 1) Cleared the Cache. 2) Clear all youtube cookies. 3) Update Shockwave plug-in. 4) Update Flash Player plug-in. 5) Cancel Hardware Acceleration. 6) Finally I upgraded Fire Fox from 8.0 to 12.
Then reloaded youtube page . . . every thing worked just FINE . . .
