Mozilla released fixes for its Firefox browser on Friday that addressed several security vulnerabilities.

Users are encouraged to update to Firefox to address the two flaws, a location.hostname vulnerability disclosed in mid-February by researcher Michal Zalewski and a critical memory corruption bug that can lead to crashes.

"Due to the security fixes, we strongly recommend that all Firefox users upgrade to these latest releases," Mozilla representatives wrote on its development site.

Mozilla worked quickly to fix the flaw discovered by Zalewski, said Mike Schroepfer, vice president of engineering at Mozilla.

"Thanks to the work of our contributors we have been able to address these issues quickly in order to minimise the security risk to Firefox users," Schroepfer said in a statement.
