On Ununtu 24.04 I did an update and youtube doesn't work on FIrefox 152.0.4. I did an update from the Software updater and videos don't play on youtube any more. I go to youtube, click on a suggested video and it goes to that page and everything shows up except the video window. I have the title and the comments and the row of suggested videos on the right, but no video player and no video. Someone suggested I push the F12 key and look under console and there is an error there, a sourcemap error and that it isn't a valid URL . I don't know what that means. I asked on the AskUbuntu site but they get really far down in the weeds and I have no idea what they are asking or saying. I thought I'd see if you guys might know. thanks
