I can't play youtube videos anymore for some reason. My browser{safari} does not support any of the player formats.
MacBook Pro (15-inch Mid 2012), OS X El Capitan (10.11.5), null
Please disable all Safari extensions and test. If the problem is resolved, re-enable the extensions one or a few at a time until you find the culprit.
Hi Linc,
This worked for me in OS Sierra (10.12.1) and the culprits were the "Click to Plugin" and "Click to Flash" extensions.
Best regards
See if installing Flash Player helps. If not, uninstall it.
Adobe Flash Player
Adobe Flash Uninstaller
This worked for me. I have not yet isolated the conflicting extension
