The seventh maintainance releae of the popular Firefox 3 browser has been released. Bringing fixes for several security exploits, improve stability and more.

As expected with this release several security exploits were plugged. Three are in the category of critical and concern: an upgraded PNG library to fix memory safety hazards, XUL linked clones fix to avoid crashes, and evidence of memory corruption leading to crashes. One high severity exists related to XML data theft via RDFXMLDataSource and cross-domain redirect, while one low severity concerns URL spoofing with invisible control characters.

Other fixes include stability, accessibility and more. This new release is a recommended update for Firefox 3 users, and can be obtained either automatically (when Firefox notifies you), through Help -> Check for Updates... or by downloading the full installer from Mozilla's web site.
