This wasn't happening yesterday but now it is.

YouTube videos aren't playing on my FireFox 17.0.1

It either buffers constantly or says "An error occurred. Please try again later"

I don't have anything called "Video DownloadHelper" on my FireFox that I just Googled and it said to get rid of. I don't have anything like that in my add-ons.

I tried clearing my cookies and my cache and that didn't work.

Can someone help me out here please? I'd really appreciate it.

Thanks.Have you tried any other browsers?truenorthQuote from: truenorth on December 26, 2012, 03:36:55 PM

Are you inside a school or other organization, or do you use a proxy?

At my school, there is a content filter/proxy (which I'm pretty sure has some glaring bugs...) that requires login with student ID / password. Some globally unblocked websites (such as youtube) will load, but the domains the videos are hosted on are unblocked when logged in. If you're not logged in to the filter, no video works, period. Issues similar to this are common with this particular proxy...

Bottom line: I see this issue often if you can access youtube.com, but you can't access the other related domains that youtube stores the actual videos on.

Uh... no. I'm at home.

Are you running any plugin-blockers, ad-blockers, or script blockers?

If you run 'ping ytimg.com' from a command prompt (Start -> Run -> cmd)
it should look something like this:

Code: [Select]C:\Users\Blah>ping ytimg.com

If it says request timed out then you're not connecting to youtube's content server.

Also... I just tried it on my laptop, which also has FireFox 17.0.1 and it's working fine. Which means it's some sort of issues on my desktop computer.
