Suddenly, I cannot get videos on cbs.com to play in Firefox. They did a few weeks ago. So far, other video sites that I use are okay.
On an older version of Firefox, the advertisement plays, then a still photo related to the video appears where the video should be, and that's it.
On the newest version of Firefox, there is a black box, no ad, nothing happens.
There are no add-ons as I (re)/installed each new.
Flash player is up to date and active.
Is there a way to get this to work again? Thanks.
