[This is all my opinion and experience, based on 15+ years of use with Firefox and extensions. Your results may vary.] After its mid-2025 "updates," VDH has become a 95% useless & untrustworthy zero-star extension. Usually fails at its ONE job of finding and downloading videos easily and correctly on demand. Asks for permissions it does NOT need to work. When it does manage to find a video, you're limited to 1 download every 2 hours (and that download will usually fail before complete) -- unless you pay for a subscription. Downloaded videos may have huge ugly watermarks on them, rendering this extension even more useless & aggravating. I can no longer trust this extension; everything about it is now inferior, worse performing, and more expensive now. Avoid this one like a literal plague.
