Controlling Preferences

In Fiddler 2.2.6.5 and later, users can control preferences using the QuickExec box below the session list.

You can view and edit preferences by typing:

about:config

You can view the current preference settings in a simple message box by typing:

prefs show

You can view the current preference settings matching a partial search string by typing:

prefs show PARTIALSTRINGTOMATCH

Note: You can hit CTRL+C to copy the message box's text to the system clipboard.

You can set a preference by typing the preference name and a new value:

prefs set fiddler.test.testpref.enabled True

You can remove a preference setting by typing the name of the preference:

prefs remove fiddler.test.testpref.enabled

Developers can control preferences directly by interacting with the FiddlerApplication.Prefs object.
