Hi, Thank you for reaching out! First, please try these standard troubleshooting steps that may resolve the issue: # Please check if you have Enhanced Tracking Protection (ETP) enabled. You can do that by clicking the shield [[Image:Fx89ShieldIcon]] icon at the left of the address bar. #* If ETP is enabled, try disabling it. # If the problem is not fixed, try [[How to clear the Firefox cache | clearing Firefox cache]]. # If it does not help, also try [[Clear cookies and site data in Firefox | clearing cookies and data]] for Soundclud (''warning: you will be logged out on this website''). # If it also does not help, try [[Diagnose Firefox issues using Troubleshoot Mode | running Firefox in Troubleshoot Mode]]. If the problem doesn't persist, please follow the steps from [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems | this article]] to troubleshoot further. Looking forward to your update on how it goes!

I will see if I can gather more information and try to debug it. But for the record, the same problem is happening on another computer I own, which is completely different from the first one. The first machine is Intel, while the second is a laptop fully based on AMD. A screenshot from the second one is attached.
