I have a problem with playing youtube video's on Firefox for a while now.

I am running this on the newest firefox on a Dell Latitude D430 1,33Ghz Core2Duo 64bit 2GB mem Windows7 x64 SP1. The problem is that there is a lot of breaking up in audio and video while even loading the video at 360P In the meanwhile, Internet Explorer runs the same Youtube video 720P without hick-ups in any kind.

Looking at the progress download bar, it holds for a while then loads again, at these moments, the inconsistencies are even worse.

I Have the same problem on my Phenom X4 940 PC with 8GB memory and a AMD HD6870 videocard with newest drivers running on a stripe raid SSD Corsair GT hard drive with Windows 7 x64 SP1.

It doesn't matter if I run firefox with or without the plugins and add-ons or without, (after restart fifo ofc) Or even reinstalling Firefox.

My Notebook is able to run 720P material without any problem. CPU usage is at an average of 70% which is more then enough reserve for background processes. My PC is able to run 2560x1600 without any problem. CPU usage is at an average of 60% which also has enough reserve. This ofc is when the video's are run from the harddrive or even USB.

In both cases, firefox is running terrible trying to play a youtube video. Internet explorer and Chrome is running fine.

Oh and my internet is a 60Mbit up and 6 Mbit down cable connection.

How to fix these problems? I already fixed the Google Maps bug due to Ghostery.

Hello,

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

  1. Go to Firefox > Help > Troubleshooting Information.
  2. Click the "Reset Firefox" button.
  3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
  4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank you.

And install ONLY one Adblocker, using Adblock Plus and Edge causes problems.

Thanks for your input.

Don't see how this is different from uninstalling firefox and deleting everything and reinstalling or disabling all plugins/add-on which I already tried as written in the initial info. But tried it anyway. (I'd try anything at the moment not having to switch browsers if this problem doesn't solve itself.)

No improvements, difference or whatsoever.

Sorry, forgot to mention. I even reinstalled my Windows 7 due to hardware related malfunction this week. So everything has the newest driver and software functions.
