Update upset

[beacon1414]

I had a pop-up about updating to 19.0.3.0, and agreed. Immediately the videos stopped working. I had been using Slimjet on the Independent newspaper site, and after the update, there was a message that videos were not available as not supported on this browser. I went to Firefox and had no problem, so the update seems to have caused the disruption. Please could someone suggest a way to restore the service or, if not, how to go back to the previous version.
Many thanks.

Are you on linux or mac? If so you need to replace the slimjet libffmpeg. I grab the one from chromium myself.
