With the new update to QMO, The "hunt down bugs" and "test Mozilla web sites" links under "Testing and Quality Assurance" need to be updated. Aakash, can you please provide the new corrected urls?
I believe that needs to be under http://quality.mozilla.org/teams/services/ and http://quality.mozilla.org/teams/webqa/ respectively.
Thanks for letting me know about the QMO changes. I just updated the links and rewrote the testing section a bit on the Contribute page. Might want to add redirects on QMO for those old links.
