Type: Feature Request
Opening two instances of fiddler traces
This would be useful to compare a completed working trace versus a non-working trace, side by side and see what the difference in the traces are.

I wanted to let everyone know that the Fiddler Everywhere has a dedicated Compare tab that allows you to inspect and compare two or more sessions simultaneously. You can compare saved session snapshots 

or various session entries from the Live traffic grid or loaded snapshots

I know this request is like 6 years old, but this is the top hit in Bing for this question.  To open two instances of fiddler, open fiddler classic and under the File menu select "New Viewer".  HTH

File > New Viewer.

Alternatively, see the Traffic Differ extension from http://www.telerik.com/fiddler/add-ons
