I am running firefox 42.0b2, adobe flash player is up to date, and when trying to watch shows on the xfinity website, it continually crashes my flash. I have tried many websites that use flash, and this is the only one I am having a problem with.
The ads will play just fine, time for the show, then flash crashes, it asks me to reload page, ads play... again... just fine, time for the show, flash crashes again. This cycle keeps going.
It didn't used to be this way. Last season, I sat here and watched all my shows on the website, now I can't watch any. And if it does let me start a show, it starts the crash cycle at the first ad spot.
