Firefox no longer picking up video feeds

by bvanmetre / May 30, 2010 4:31 PM PDT

Evening all, I was just wondering if people were having trouble playing back streaming video off of sites like, UStream,, etc. Seems a couple of weeks ago, around the time Firefox updated last, this feature stopped working. No Script, an add-on I've been using and love also updated close to the same time as well. I've used both programs with great success on these sites before except that now, even though neither of their settings have changed, I can't play back anything. I'm stuck using IE! Ugh! Now, 3 of my machines, all different makes and models, are having the exact same problem. I've included their specs here, but I really feel that it has something to do with Firefox and/or an add-on. Taking the No Script off, doesn't seem to help either. Any thoughts anyone?

They seem to work for me

I'm using Firefox v 3.6.3 and have just tried both and UStream.

In fact I watched the Stork Nest Live from Dumbravioara, Romania, Europe in, Happy

I didn't try the site.

You don't say what happens when you get to these sites with the video feeds. Do you get a blank video placeholder, or error messages? Both the two I tried use Adobe's Flash Player 10, and my guess is that your Firefox Adobe Flash player is either disabled, or is no longer working.

You can check if the plugin is disabled by going to Firefox > Tools > Add-ons, then the Plugins tab. If it is enabled, then I would re-install Adobe.

To do that, I would first use Adobe's Flash Uninstaller tool to remove all traces of Flash, reboot the system, (just to make sure the registry is properly updated), then re-install Flash.

How to uninstall the Adobe Flash Player.

Install Adobe Flash Player - BEWARE, note the option to include "Free McAfee

Attempted the uninstall/reinstall of Flash

You were right in that I forgot to say what happened when I tried to pull the videos up. The page loads, but the actual stream stays black, doesn't show anything, including any embeded controls or the like. The rest of the page however loads up just fine even when I allow all scripts to run. So I downloaded the uninstaller, closed everything, uninstalled Flash, rebooted, re-installed flash and still have the same problem. The Shockwave Flash player is enabled in my Add-ons, and when I go to the Adobe site itself, all the Flash stuff works. It just seems to be limited to these specific sites for some reason. Any other thoughts?

Hmm strange.

I'm not sure how to proceed with this problem.

Videos work in IE but not in Firefox, and you have uninstalled and re-installed Adobe's Flash.

Try clearing Firefox's cache;

1. Launch Firefox
2. Select Tools > Clear Recent History
3. In the Clear Recent History pop-up, select "Everything" from the Time range to clear drop-down list box
4. Click on Clear Now
5. Close Firefox and re-launch

Is it just these 3 sites, or all sites that show Flash Videos?

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
