Hi and welcome to the forum
I've seen this particular problem before on both facebook and YouTube; some videos are intentionally designed to do that in order to grab your attention and play them. They will never work properly. Sometimes those weird videos contain viruses/malware.
If your other browsers such as Chrome or IE11 are playing the videos Ok; it could simply be settings in your Edge. I suggest you do a reset on Edge or use a safe program such as
CCLEANER from
PIRIFORM.COM to delete the cookies. Often this will resolve the problem.
If your Edge still doesn't work after trying these things, it's likely it's one of the new viruses that are specifically designed to attack the Edge browser as now about 400 million people are running W10 according to Microsoft--and those computers all have Edge on them. They are ripe for virus/malware attack.
I suggest you use whatever AV program you have running, make sure you update it first and scan/remove all found viruses. Next, visit
MALWAREBYTES.ORG and download the free Malwarebytes antispyware program and scan/remove all found spyware viruses. Finally, visit
TRENDMICRO.COM and check for Rootkits/Bootkits with the free
ROOTKITBUSTER. Reboot your computer and retest your videos with Edge. If they not play correctly, you had viruses/malware infecting your computer and once removed your videos should play normally!
Best of luck,
