I finally found one that works (mostly - sometimes I have to reload the page multiple times)! I tried extension after extension. At least 10 of them. Some of them were very highly-rated. None of them would download a video with audio from FB. All but one of them would not even detect the video. The one that would detect it downloaded without audio. This one worked. Too bad it doesn't grab the name of the video as the filename.

Basic and working (as of today). However, it doesn't appear to be able to download the best resolution possible.
