Just installed 184.108.40.206. Selected to decrypt HTTPS, exported the Fiddler self-signed root, imported it under Windows 7 Trusted Root CA using certmgr.msc, and verified Windows trusts it. Then imported it into Firefox 44.0.2 Advanced > Certificates > View Certificates > Authorities with Trust Setting to Identify Websites. Every https reference when Fiddler is running, regardless of browser, gives "Your connection is not secure" error. If I close Fiddler, no errors. Rebooted, no change. Not sure what I'm doing wrong.
