Watch this site http://www.cbsnews.com/video/ Why doesn't another video follow, only first plays. But Google Chrome plays all video clips consecutively.

You most likely have disabled websites from refreshing/redirecting.

It can be found in the options as seen in the screenshot.

It didn't help unfortunately

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

• Do NOT click the Reset button on the Safe Mode start window.

The problem is remaining. I started Firefox in Safe Mode, DEFAULT theme standed alredy then I downloaded http://www.cbsnews.com/video/ but it plays only 1st vidio. I also updated Abobe Flash Player. No result.
