The key to improving Firefox security: Multiple processes That four separate vulnerabilities were found in Firefox at Pwn2Own 2014, however, is impressive.

Since 2012, however, as security researchers have grown ever more wiley, every major browser has fallen to at least one zero-day vulnerability. While Chrome went unhacked in 2009, 2010, and 2011, the only year that Firefox wasn’t hacked was 2011.

While the format of the contest has generally changed every year since its inauguration in 2007 (different platforms, different rules, different attack vectors), Firefox has been involved in some way or another since 2009.

At Pwn2Own 2014, an annual computer hackfest in Vancouver, Mozilla’s Firefox has proven yet again that it’s the least secure major web browser.
