Mozilla Firefox, one of the world’s most popular browsers, has been updated. However, as we know that Firefox 4 already comes with new design, so this update, of course, does not make any design changes in any way. Therefore, this time the update brings with it closing of security vulnerabilities and many stabilization works. In short, Firefox 4.0.1 is out. As Teknobeyin, we recommend that you update your Firefox browser. At least, even the removal of security vulnerabilities should be a reason, or rather an important reason to update.
