Cursor Autohide for Disney+ by Carolina

On Firefox for macOS, the Disney+ player never hides the cursor during playback, so the pointer sits on top of the video until you move it away. YouTube hides the cursor in the same browser, and Disney+ hides it in Safari, which points to Disney+'s idle detection misbehaving in Firefox.

If you aren't using macOS and experience this same issue, this extension should still also fix your issue.

This extension runs its own idle timer and leaves Disney+'s player alone. It uses none of Disney+'s code.
