Hi, I use the Firefox Developer Edition for Windows Desktop (112.0b4 (64-bit) on daily basis. When I play the Udemy DRM content nothing goes wrong first and the browser loads the page well. But after some time passed I see that Firefox stops to load the page and the tab spinning infinitely. Pressing the realod button doesn't help. The only solution is to restart the browser. I use no-proxy setting. The refreshing of the browser didn't help either. I have configured the following options in the "about:config" but it didn't help as well: network.dns.disableIPv6 : true network.dns.disablePrefetch : true network.http.http3.enabled: false

As I currently use the latest Developer Edition, the problem seems to get resolved in the version 112.0b9

This is why it's a good idea to run multiple versions of the Firefox to test these issues. I typed in the url from your screenshot and the site changed it to below address, but it worked for me running 111.0.1. see screenshot https://globallogic.udemy.com?next=%2Fcourse%2Flinuxforbeginners%2Flearn%2Flecture%2F967046#overview Is that a bookmark you clicked on to get that url? Do we need to login to replicate your steps to get to that point?

As I said the problem seems to get gone in the 112.0b9 (64-bit) version of FDE . The problem with the audio cracking is still may be noticed randomly on the speed 1.75 and higher.
