hello,

         i think you have to change some firewall settings . All versions of Windows each have slightly different ways to configure the built-in Firewall, but they are fairly close once you find your Control Panel. Instructions for configuring the Windows 7 Firewall to open the required ports are below.

 1)  Click Start
 2)  Click Control Panel
 3) Click System and Security
 4)  Click Windows Firewall
 5)  Click Advanced Setings
 6)  Click Inbound Rules
 7)  Under Actions, click New Rule
 8)  Select the "Port" option and click Next
 9)  In the "Specific Local Ports" box, type the following: 80, 8080, 8000, 50000, 53, 443, 843
10) Select "Allow the Connection"
 11)Select a Network type and click Next
   12)Name the rule
  13) Click Finish

If you are still have problem after doing this firewall settings . reply us

                          thank you ,

type these ports also1935 , 1935, 80, 8134, 1111.

Bizarre behaviour noticed... I was reseaching other folks posts who had reported problems with "Youtube.com", and just for curiosity, I clicked a blue highlighted "Youtube.com" link. This took me directly to the Youtube page, and *rendered it correctly*, complete with full-motion video in high-res, in the advert. I noticed that when I entered "http://www.youtube.com" in the command line of Firefox 34.0.5, it would be translated to: "https://www.youtube.com". I thought this was Google doing it, but maybe not. I noticed there was some kind of "https for everything" feature on the "Tools" menu of the Tor-firefox browser. Tor does not have any "uninstall" program associated with it. If I can nail down exactly what is happening, I will report the results here. - Mark

The firewall is not the issue. I simply disabled the firewall, and confirmed that same rendering problem exists. And, I cannot replicate whatever happened to allow the Youtube.com site to render, when it did. Only way I can see any Youtube videos, is with Tor-Firefox (version 4.0.2 Tor, which uses ver. 31.x of Firefox), and only with Tor running, which makes video streaming way too slow. Problem not solved. The main "Youtube.com" page does not render correctly (see the .jpg image), and no Youtube.com videos at all can be viewed. All Youtube.com videos report as "This video is unavailable." - Mark

Got it! I have spent *days* on this, because it just bugged me so much!

FOund it by searching and reading all the "youtube"-related Mozilla FIrefox support forums. Thx guys.

Problem was an old hard-coded fix that I put into my HOSTS file, on my Windows XP, SP3 machine. Specifically, I had experienced hang issues with a site called "i.ytimg.com", which I believe is the static cache for Google/Youtube stuff. I tracked this error down to failures of security certificates, but confirmed my security cert store was isometric between my machine cluster (they were all the damn same!) So, I had put two lines in the HOSTS file, to hard-code an IP address so that Google-youtube pages would not hang up waiting for "i.ytimg.com" Well, of course, Google/Youtube is now using different locations, or akami servers or some damn thing...

The fix just involved removing these two hard-coded lines from my HOSTS file. I just commented the old fix out, and now everything works.

# --- two lines added to fix i.ytimg.com hang problem
# 74.125.162.39        static.cache.l.google.com   s.ytimg.com
# 74.125.162.39        static.cache.l.google.com   i.ytimg.com

(The # symbol is used to make a comment in hosts file... )

On Windows XP, XP3, the "hosts" file is typically located in:

     C:\WINDOWS\system32\drivers\etc\hosts

If you are having goofy problems with some youtube/google webpages not rendering, or generating SSL (bad_certificate) errors, check your "hosts" file, and ensure no ip redirection has been slotted in there from a while back.

Hope this helps others... - Mark Langdon, GEMESYS Ltd.
