Description I tested this in the latest Nightly of Firefox 55.0a1 (2017-05-30).
Open https://www.food.ee/restaurants/vancouver/
Open the Netmonitor panel (make sure the debugger was not init first)
Click on the "Show filters" button in the page (top right, above the list of restaurants)
A new request should have appears in the Netmonitor
Click on the [JS] icon in the request row in order to open the stack trace sidebar panel
In the sidebar panel, find the openFilterPanel frame and click on the link to the source code next to it
This does not do anything, which might be related to source maps, or the netmonitor, or the debugger, not sure
Now, click on the Debugger tab to switch to it manually instead
the debugger is blank at this stage
An error also appears in the browser console:
TypeError: pendingBreakpoint is undefined[Learn More] debugger.js:16544:10
