Anyone making use of the Firefox 3.5.x branch will want to snag the latest update, which Mozilla has just pushed out. Firefox 3.5.3 is now available for download and is primarily focused on security and stability. A total of nine bugs marked as “Critical” were taken care of, among a laundry list of 43 total, including some related to memory corruption problems.

The new version also warns users if they are using outdated versions of Adobe's Flash Player, a feature that should extend to other popular plug-ins in future releases. If you're one of the 3.0.x branch users who have been suffering from upgrade woes when trying 3.5, you may want to give it another shot – the fix list for 3.5.3 is pretty large and hopefully solves many of the crashing issues that earlier versions have suffered.
