Did you contact the site to ask if there was a configuration issue? Sometimes if you use safe mode that will stop since streaming sites requires tracking and cookies to insure your the one the same person.

The behavior was the same whether I was in safe mode or not. I did not contact the site because they all worked in IE. I just assumed that if a site works in one browser but not another, it's the browsers fault. Did you try the links? Did they work for you?

Sorry, the post I chose as "mark a solution" was not the solution. But it was the only way I could get back to this page as my bookmark to here was deleted. My 'FIX", was to close FF. Enable hidden files/folder, browse through my user folder and delete everything (including sub folders) that had the word "Mozilla", essentially deleting my profile. After restarting FF, it created a new profile and all of the streams worked correctly. I knew it wasn't a problem with the sites/network, which is why I didn't contact them. I knew it was a problem with FF, I just didn't know what. Apparently, it was some setting I changed at some time that caused it. Unfortunately, my "scorched earth" approach at troubleshooting wiped out all my customizations, but it's not really that big of a deal as I had a somewhat recent backup of my bookmarks and everything else is just a handful of addons and UI settings. But, I had been wanting to change browsers for a while now and this gave me an excuse. I have used FF for a loooooong time, and, IMO, it has been going downhill for a while. Starting with the whole "Australis" thing and culminating in the "Quantum" thing. While I do appreciate the support you guys give here, it's a bit like an ambulance following a drunk driver, you don't stop the damage, you just try and patch it up afterwards. I found that I spent more time googleing "How do I make Firefox...." more than I spent actually surfing, combined with having to "end process" FF several times a day because it would freeze. Regardless, I'm done. So long, and thanks for all the fish.
