Yesterday I was playing around with some XUL stuff (I really like it ) and so I came across a list of Firefox chrome URLs. Now have a look at the following three lines:

chrome://pippki/content/editcacert.xul -> Crashes browser when opened
chrome://pippki/content/editemailcert.xul -> Crashes browser when opened
chrome://pippki/content/editsslcert.xul -> Crashes browser when opened

Just put one of the above chrome URLs into your URL bar and hit Enter. Thanks to mozillazine.org for give us this useful information.

OK, what do we learn here: If you’re looking for a vulnerability, just browse the Internet and wait
