Ever since Firefox updated, videos are stretched on the right hand side, the other half of the video appears fine. This is only for Firefox, not other browsers
Whenever a video plays, half of the screen is stretched to the right, and the left half appears normal. I thought maybe it was my computer, but I tried chrome and there are no issues.

See if there are updates for your graphics drivers https://support.mozilla.org/kb/upgrade-graphics-drivers-use-hardware-acceleration
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).
Is the problem still there?
