Created attachment 757061 [details] screen shot.png User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20100101 Firefox/21.0 (Beta/Release) Build ID: 20130511120803 Steps to reproduce: I opened QMO link How to Write a Proper Bug. Then clicked on link " Nightly Tester Tools ". It takes on an dead link page. Screen shot is attached. Actual results: A page "Sorry, we couldn’t find that" appeared. Expected results: A page giving the information regarding the nightly tester tools should come.
Thanks for the bug report. I've updated the link to point to the extension on addons.mozilla.org.
