I have been using Firefox for years and I had to leave Firefox for almost a year because the autoplay on Youtube never works properly. On some videos we can see the ON/OFF button at the bottom of the screen on other videos it is not accessible. All the settings are adjusted properly... I have to use another browser to listen to music. when I use for example EDGE or Chrome there is no problem at all, I can leave the music playing all day even if it is not a playlist the minutes that I go on Firefox I have to constantly restart the video again because it stops automatically it is not my computer it is your Browser that does not work well. Moreover, when I try to synchronize my old setup that I already had impossible.... it is always to be redone continuously you have made significant changes and progress I find it very unfortunate. In conclusion, you should enable custom background on the main page we're in 2025.. I hope that you will answer me even if I really doubt because you don't really care about custom services have a good day
