I found the problem. As of yesterday, Firefox videos no longer work with Adblock. (They work when I disable Adblock.) So the solution is simple: permanently switch to Chrome, which plays all videos with Adblock.

You shouldn't have any issues with using Adblock and playing videos. Please ensure that you have the Adblock Plus add-on and not a fake copy.

Nevertheless, Mozilla does not develop or maintain add-ons, so you will need to get into touch with the Adblock team to advise them about the issue. You can also add the websites with issues to the whitelist.

Sorry for any inconvenience.
