How to fully reset Fiddler Web Debugger Tool

If you have any problems with Fiddler and you can't figure it out what's going on, follow this guide to fully reset Fiddler. Press SHIFT and launch Fiddler does not really help.

Open regedit.exe, navigate to " HKEY_CURRENT_USER\Software\Microsoft\". right click on Fiddler2 folder, and delete it.


Open My documents and delete Fiddler2 folder


Launch Fiddler. Open Options -> HTTPS, click on Actions -> Reset All Certificates. It will ask you to reset, and add certificate. Click OK or Yes when asked.

That's all. Fiddler should work correctly again as it should :)
