From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.0rc1) Gecko/20020417 BuildID: 2002041711 if using a js debugger and you click on error you get source... I haven't found a good way to get the line number on the html source code... need a hotkey or perhaps a menu item that adds this functionality. Reproducible: Always Steps to Reproduce: 1.View Source/View Page Source/View Frame Source 2.Open Up JS Debugger/ Follow Link that has js exception/error 3. Actual Results: this is more of an enhancement than bug.. Although this should have been added in previous to now. Having to trace through html code to find a line number is a huge hassle if you're viewing source through the browser or composer.

this RFE should be well covered in these: bug 15364, bug 99211, bug 79612, bug 104383 *** This bug has been marked as a duplicate of 79612 ***
