videoSiphon

Doesn't work, will just charge you $1 for their "free" trial and then provide no key. Also REALLY suspicious that it reloads all tabs when installed, never had an extension do that without asking me before. STAY AWAY. You might be able to download wistia videos if you are handy with the "inspect element" option and google.

I've tried several similar extensions but none of them was able to download vimeo videos as a single videofile. This extension has done it for me. love it

Stupid. Downloaded to try for 7 days and got no license number to plugin so I couldn't even use it. If you want to sell hamburgers, you'd better have some ground beef.
