After updating to Thunderbird 60.3.0 the YouTube messages no longer show the preview image of the video. I started Thunderbird in safe mode and the images still don't show. Even older messages I received before the update that did show the preview image now after the update no longer show the image. Oh and I have also enabled "Allow remote content in messages".

Well, I found the problem. I started comparing the about:config of my Thunderbird install with one that didn't have this problem. During the last Thunderbird update for some reason the: Browser.Display.Document_Color_use was set to the value of 2. When changed it to its default value of 0 now things are working correctly.
