In every and all youtube videos I watch, the video jumps and freezes five seconds in while the audio plays, and then when the audio reaches five seconds, the video starts to play and they're in sync.

I've tried to refresh Firefox but the problem still remains, I have the latests Firefox update, I've tried youtube on Chrome and didn't have the same problem, and everything works fine when I try it on my phone.

I appreciate any and all help :)

Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.

Flash: Grab the uninstaller from here: Uninstall Flash Player | Windows Uninstall Flash Player | Mac

Then reinstall the latest version.

Note: Windows users should download the active_x for Internet Explorer. and the plugin for Plugin-based browsers (like Firefox).

Note: Windows 8 and Windows 10 have built-in flash players and Adobe will cause a conflict. Install the plugin only. Not the active_x.
