certain web sites will not play video
Recently migrated to Firefox from MS Edge. Now I can't watch videos on NHL.com and NFL.com. These just have black boxes where video should be. Bleacher report doesn't fill in all news feed article links, pictures etc. Other pages work fine with embedded video. You tube works. Did set up privacy extensions so not sure if there is a conflict with one of them. Any guidance is greatly appreciated.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.
- make sure your extensions and filters are updated to the latest version

Firefox shows the shield icon at the left end of the location/address bar in case Content Blocking is blocking content.
