Thanks for the report!

Any chance you could provide a test case (your page with JS files), so we can reproduce the problem on our machines?

If loading e.g. google.com page I can see JS files in the Debugger Sources panel

As said, this only happens on local URLs (file:///, localhost, http://mylocalwebsite/index.html...). You can save the file I just attached and open it with Firefox Developer Edition and for me, it isn't allowing me to put a breakpoint on the JS. I'm using the version 84.0b7 that I downloaded on the mozilla website, on Linux Mint x64.

Thanks Flaburgan,
We are not able to reproduce it on Windows and MAC, and wondering if this an Ubuntu specific issue.

Also would you be able to test on the latest nightly which is version 85?

There is also work going on which might be related to your issue. See Bug 1678254 for details.
