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.

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)
