Firefox v. 56 -- Why do Fox News and other videos work only in safe mode?
I am using Firefox 56.0 on Windows 10 (1703) 64 bit. Videos on many sites, including Fox News, work only in safe mode. On other websites, video works fine. I have tried all the knowledge base suggestions including disabling (and finally deleting) all added on extensions, disabling hardware acceleration, and clearing the cache, history, and cookies. I also cleared the DNS cache. Nothing works for these sites except opening Firefox in safe mode. Otherwise, the video screen is just black (no loading symbol). I have no trouble with video on these websites on other browsers.
Any suggestions would be greatly appreciated.

Thanks for all your replies. I tried all the suggestions but nothing worked. I isolated the problem to my profile, but it was not related to any add-ons, plugins, or external programs like Rapport. Since I couldn't isolate the cause, I finally decided to save my bookmarks, history, and cookies, delete my profile, and start fresh with v. 57 beta. Now video is working fine. Just to check, I reinstalled v. 56 with my new profile and everything worked fine there too. I'm sticking with v. 57. It's really fast and I like the new features.

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes). If the problem goes away, that tells us one thing. If it does not, that tells us something else.
An add-on may be blocking content.
It could be IBM Security Rapport 1.4, is there a newer version ?
Fyi: Your Flash is out of date, please update to current version https://get.adobe.com/flashplayer/otherversions/ Step 1: Select Operating System Step 2: Select A Version (Firefox, Win IE . . . .) Note: Other software is offered in the download. <Windows Only>
After Note that some sites use in their code both Flash and Html5 and the browser picks. Which one it decides I do not know.

Please let us know if this solved your issue or if need further assistance.
One other thing to be on the lookout for is Tracking Protection in private windows. You'll see a "shield" icon toward the left end of the address bar when it is filtering out some content in a page. More info: What happened to Tracking Protection?.
