In Facebook, I've this message when Facebook Tracking Removal 1.3.5 is activated "Video format or MIME type is not supported". TIA for a solution. Without this problem, 5 stars.
I'm aware of the problem and its cause, but haven't had the time to work out a solution yet. You can fix the issue without removing the plugin by disabling the video setting in the options.
In case you're interested, the issue has to do with Facebook recently starting to use blob URLs in certain videos.
