FireFox 3.0.2 Released – 11 Bugs Fixed – Update Today!

The latest update of FireFox version 3.0.2 now available for download includes patches for 11 security deficiencies, many of them rated as critical by Mozilla Corporation.

If you are still using FireFox version 2, then you need to update this version as well, since the latest release of this version includes 14 patches. A number of patches in version 2 are exclusive to this specific version.

Frankly, if you are still using version 2 you need to take the plunge and update to version 3 now. There is no guarantee that Mozilla will continue to offer support for version 2.

A number of the vulnerabilities in version 3 were serious, and included stability issues related to graphics rendering, layout and JavaScript engines. Each has the potential to cause browser crashes could potentially leave the user open to exploitation by malicious code.

The latest FireFox security advisory lists the following vulnerabilities as having been patched.
