Less than a month after release, Firefox 3.5 receives an incremental update bringing the most current stable version to 3.5.1. As might be expected, the 3.5.1 update addresses several security and stability issues, as well as an issue that was making Firefox take a long time to load on some Windows systems, Mozilla says.

"We strongly recommend that all Firefox 3.5 users upgrade to this release," Mozilla said in a statement. "If you already have Firefox 3.5, you will receive an automated update notification within 24 to 48 hours. This update can also be applied manually by selecting 'Check for Updates...' from the Help menu."

On a related note, Mozilla said it is no longer supporting supporting Firefox 2.0.0.x, which "contains known security vulnerabilities." So in other words, pretty much every Firefox user should go grab the latest update.
