With Firefox v101 I can no longer decrypt HTTPS with Fiddler Classic.
I reset Fiddler's Root Certificate multiple times to no avail.
When the same is tested in MS Edge, no problem

We made comprehensive testing with the latest version of 64-bit Firefox on Windows 10 and Windows 11, and the HTTPS traffic capturing is working as expected on our side. That said, you may have a specific misconfiguration that prevents Firefox from using the FIddler proxy properly.
The first thing to check is if Firefox going through the Fiddler proxy at all? You can check that by trying to capture traffic from non-secure sites like http://example.com
