video links.
When I open this page it should show video clips for each exercise but it just shows a black space instead. It used to show the videos! There's probably a setting I need to change but I don't know what.

Make sure you are not blocking content.
Start Firefox in Safe Mode {web link}
A small dialog should appear. Click
Start In Safe Mode (not Refresh).
Is the problem still there?
