On Wednesday (Aug 29th, 2007) at around 11am the Snap Shots Add-On for Firefox was approved and posted to the Mozilla Add-Ons site...

This is a monumental occasion for us here at Snap as we love and support Firefox/Mozilla and are honored to have been reviewed and chosen to be presented on the site. We look forward to the downloads and commentary from their family of Firefox users...
