How can I watch a lecture from videolectures.net on a Mac? I have OSX 10.12.6 and the Flip4Mac is not working/outdated (in particular, this link on the help page has expired. I just downloaded Chrome, so I'm not sure what's going on when I receive the following error message:

Your browser does not support playback of available video formats. Please install Adobe Flash player or upgrade to a more modern browser.

I also tried on Safari and Chromium after downloading Adobe Flash...

Tried Firefox just now and it worked
