The link formatting syntax here (and elsewhere on this page) is incorrect and throwing errors.

I believe it should be along the lines of:

`{{_('Lightbeam began in July 2011 as Collusion, a personal project by Mozilla software developer <a href="%s" target="_blank">Atul Varma</a>.')|format('http://www.toolness.com/wp/')}}`

Apply this to similar blocks below and you should all be set, thanks!
