In Firefox, the scrolling arrows are not appearing when taking a capture.
Reason 1: Fails on First Attempt
When a new Firefox session is started, the scrolling arrows will not appear on the first capture attempt. Cancel the capture, and try the scrolling capture again.

- Select the Security & Privacy panel.
- Go to the Permissions section.
- Deselect the Prevent accessibility services from accessing your browser checkbox.
