The Mozilla Foundation has released Firefox 10, the latest version of their web browser, which fixes eight vulnerabilities, six of which are rated critical. These include memory corruption issues, cross-scripting vulnerabilities and more. (See the Firefox security advisory.)
Firefox 10 also features some “powerful new developer tools,” for web designers, and a new system for checking add-on compatibility.
The Mozilla Foundation also released Firefox 3.6.26, with patches for five vulnerabilities, because some people are still using the two-year old version of the program for compatibility reasons.
Users can automatically update their copy of Firefox by launching it, choosing Firefox > About Firefox, and clicking Check for Updates. Alternatively, you can download a copy here, or, for version 3.6.26, here.
