"Mozilla Corp. late yesterday patched Firefox to quash 11 bugs, including one from three weeks ago that posed a threat to users who had installed any of the more than 600 add-ons for the open-source browser. Firefox 18.104.22.168 fixed four vulnerabilities that Mozilla ranked "critical," one it pegged "high" and three each rated as "moderate" and "low," according to the security advisory posted Thursday.
The new edition patched more flaws than any update since July 2007. Mozilla last patched Firefox in November. Although it didn’t receive Mozilla’s highest threat ranking, the vulnerability in the browser’s chrome: URI (Uniform Resource Identifier), disclosed by researcher Gerry Eisenhaur, got the most attention.
