I use a PC and Firefox is my preferred default browser.

BT Sport is virtually unwatchable in Firefox (juddering, buffering, freezing, delay) but plays pretty well (occasional judder) in Internet Explorer. Why? Do I need to alter Firefox settings? Youtube etc play perfectly well in Firefox.

Details of my system are as follows:-

Windows Vista Home Premium Service Pack 2, 32-bit OS. Internet Explorer 8. Mozilla Firefox 48. Silverlight Plug-in 5.1.50428.0 set on Always Activate. Shockwave Flash 22.0r0 set on Always Activate.

Thanks for any help you can give.

Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.

Poke around safe websites. Are there any problems?

Then restart."


Any other ideas please?

Please provide a public link to the video you are haveing the problem.

If you have problems with current Shockwave Flash plugin versions then check this:

  • see if there are updates for your graphics drivers

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
