I have just updated to 91.0b5 on a Manjaro system, and have noticed that the Debugger tab in my developer tools is completely empty. Before I try to downgrade to an earlier version I was hoping to see if there was something I could do to to resolve this.
If I kill the process and restart it with
firefox-developer-edition -jsconsole I see some errors repeated in the console which say “Error while calling actor 'breakpoint-list’s method ‘setBreakpoint’ Breakpoints expect to have ither a sourceUrl or a sourceId” and this message is repeated in several other lines printed to the console.
I rely on the debugger to do my job so I hope that this is something that others have experienced and know how to resolve.
