Type: Feature Request
Clear sessions from system tray menu


I'm developing an application with Angular using Windows Authentication.

I tend to have Fiddler running all the time as it provides the authentication (using the Fiddler Automatically Authenticate flag).

As I have it running continuously the request pane gets quite large and the memory footprint increases as a result.  This is fine, and just the nature of the beast.

Periodically I clear the request pane out with CTRL+X but I have to maximize the Fiddler window first.

It would be really helpful if there was an additional option to clear the request pane from the menu on the system tray icon (please see attached).

Many thanks, and keep up the good work.  Cracking tool.

Sweet!  It never even occurred to me to use a rule!

Many thanks,

Ah, I forgot that the context menu for the notification icon is already public. Click Rules > Customize Rules and update/add the following code:

              static function DoClear(src:Object, e: EventArgs) {


    static function OnBoot() {
var o = new System.Windows.Forms.ToolStripMenuItem("Clear Sessions");
FiddlerApplication.UI.mnuNotify.Items.Insert(0, o);

You could also bind the "Clear session list" command to a global hotkey that you can use anywhere in Windows.

Using the "Keep only" setting as a workaround makes sense, but it would also be pretty easy and simple to make the tray icon extensible (following the pattern of the existing *Action attributes on FiddlerScript functions). This could be useful for other user scenarios where there aren't great workarounds.

Have you considered limiting the number of sessions in the sessions list using the "Keep" tool from the toolbar instead of periodically clearing the accumulated sessions? If you don't need all sessions from the previous "Clear", but only few of the last sessions this would work perfectly for you.
