Compatibility: Windows

Bandicam is another Firefox screen recorder for Windows. It has capabilities to capture everything on the screen, record gameplays in 4k, and record external video devices. When you’re recording, you can draw on the screen in real-time, add webcam overlay, add a mouse click effect, and use the chroma key. Another advantage of Bandicam is that it can screen record at a specific time as long as you set a date for the recording.

Unfortunately, it sets a recording time limit for free users which allows them to record up to 10 minutes per recording. Moreover, they can’t use the scheduled recording feature and the recorded video will be watermarked.

If you want to record Firefox screen without a time limit and watermark, you’ll need to purchase Bandicam. The lifetime license costs $39.95.
