Can't download videos from facebook groups anymore

All of a sudden, videos from facebook groups cannot be downloaded. I get the message: (No links were found)!

This is a recent issue, I was able to download from facebook groups 1 or 2 weeks ago.

Public facebook videos are still working fine with the extension, but not the group videos.

• Browser: Chrome 74.0.3729 Mac OS X
• User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.131 Safari/537.36
• Extension: chameleon 8.15

Any help would be hugely appreciated, thank you!
