Request for advice for video capture.
 

I checked, and there didn't seem to be anything against this in the rules.

I usually use NetVideoHunter to capture videos I like. However, the newest Firefox (Quantum, version 57) is incompatible with NVH. I have no idea if NVH will ever be updated.

So, here's my request. Other than NetVideoHunter with Firefox, what can I use to capture videos posted online? I can find add-ons for use with YouTube, but most of what I want isn't on YT, of course.

I'd appreciate any advice anyone can give me, whether it's another add-on, another add-on with another browser, or whatever. Thank you all so much!

I'm not sure if this STICKY will help, but it's a start.
