The Mozilla Foundation-sponsored Spread Firefox marketing site is back up and running, two weeks after it was taken offline because of a second hack that may have exposed registered users' information.

In early October, the site -- which pushes for the adoption of the popular Firefox browser -- was breached by attackers using a vulnerability in installed-but-not-used software on its servers. That followed a similar incident in July.

When the site went offline earlier this month, Mozilla promised that it would recraft the Web site from the ground up.

"We’ve focussed [sic] on getting the site back up and running as quickly as we can, and we have invested time and money to create a brand new server infrastructure and we have re-built Spread Firefox from scratch upon a pure Drupal code base," wrote Mozilla's Asa Dotzler in a blog entry Tuesday.

Dotzler also noted that posting on the site has been simplified, and that future enhancements were in the works, including a collection of project management tools and language localization.

"We are about to go 'International' and expand the facilities for non-English speaking cultures to recognize the fantastic contributions we have from members all around the World," Dotzler added.

In other Firefox news, the browser will pass the 100 million download mark Wednesday. A counter on the Spread Firefox site tracks the number of downloads since the browser debuted in 2004.
