The good folks at Mozilla have released a new maintenance release of Firefox, bringing it up to 3.0.6. Although not the most exciting release, for this we have to wait till 3.1, it does contain important changes worth updating.

Most importantly are the security fixes that also appear in this release, of which one has a critical state and two high impact. The areas these fixes concern are: crashes with evidence of memory corruption (rv:1.9.0.6), XMLHttpRequest allows reading HTTPOnly cookies, Chrome privilege escalation via local .desktop files, XSS using a chrome XBL method and window.eval andl ocal file stealing with SessionStore, and directives to not cache pages ignored.

Other fixes in this release concern stability, problems with rendering of Firefox itself after long up times, improved abilities for scripting commands regarding access to plug-ins and more.

You can update your Firefox, if it hasn't asked already, by clicking Help -> Check for Updates and following the instructions. Of course you can also retrieve the full download from Mozilla's site.
