Hello, I am using the latest official Firefox build 75.0 on my Macbook Pro 15 inch 2018. Have an odd problem. When I play a video directly on YouTube, the quality is always 360p. Even when I manually switch to 1080p or 4k. It always displays the video in 360p. When the same video is embedded on another website it is possible to switch the quality (and the video is shown in 1080p and/or 4k). Can somebody help me please? It is so annoying! I have added a screenshot of my Addons if helpful. Greetings from Germany and stay healthy Jan
