Hello, I seem to have a problem with videos working on "Private Browsing". Whenever I got to certain websites, like Twitch, the Videos don't work. Youtube works fine and so do all websites on normal browsing. The videos do not just don't load on private browsing, they just stay black.

Ok ... you may have a Safari extension or third party plug-in installed that's causing a conflict; an ad blocker might be responsible.
From the Safari menu bar click Safari > Preferences then select the Extensions tab. Uninstall one extension at a time then quit and relaunch Safari to test.
If it's not an extensions issue, try troubleshooting third party plug-ins.
Back to Safari > Preferences. This time select the Security tab. Deselect: Allow Plug-ins.. Quit and relaunch Safari to test.
If that made a difference, instructions for troubleshooting plugins here.
Open System Preferences > Flash Player then select the Advanced tab.
Click Delete All under Browsing Data and Settings
Now empty the Safari cache.
From your Safari menu bar click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Now click Develop from the menu bar. From the drop down menu click Empty Caches.
Quit then relaunch Safari then try a video using, "New Private Window" from the Safari File menu.
I tried it. Unfortunately, it didn't seem to work.
