STR: 1. got to http://devtools-dash.paas.canuckistani.ca/ 2. open the inspector, inspect the #container div 3. click on a rule eg nav:after Expected: * should switch to the style editor and land on the line where this css is defined in the prettified source Actual: * opens the style editor with the line on line 9 Aside: wasn't clear to me how to tell if the pretty version of bootstrap.min.css was being prettified or loadeding original sources from a sourcemap - I'll log a bug about having some sort of visual indicator of that generally.

Line 9 is the correct line in the minified css, so the problem probably comes from the fact that the rule-view code that gets the file name and line number has no idea if the file has been/will be prettified in the style-editor.

This is actually a duplicate of bug 724505.
