User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:23.0) Gecko/20100101 Firefox/23.0 (Beta/Release) Build ID: 20130730113002 Steps to reproduce: http://jesusnjim.com/bugs/fb-invalid-quantifier.html ctrl-shift-s web console Actual results: invalid quaantifier error is given and it points to the html file, but doesn't show where. if you click on ethe error message, it just puts you at the top of the file. no line number is given in the error message. my guess is this is a pattern attribute which has this problem. also, I suspect that there are lots of these errors if it's a pattern attrib, but if it's a js regex problem, then even more so a line number should have been shown. Expected results: line number should be given and clicking on error should put you at the location of the problem. if it was a js regex problem, then a line number definitely should have been shown.

I don't see an error using steps of comment 0. Do you still see this issue in a current version of Firefox started in safe mode?
