Google had released latest version for Chrome (9.0.597.107) fixing around 19 bugs on Monday. And within no time Mozilla has also come up with latest version of Firefox (3.6.14).
Interestingly, these were released just before the Pwn2Own hacking contest (to be starting on March 9th). Even in 2010, Google released 126.96.36.1996 version, days before the contest. Apple also had released updates for Safari in 2010 in almost the same time-line. Google Chrome stood the only browser unhacked among Internet Explorer 8, Firefox 3.6 (which lead to release of 3.6.4) and Safari 4 in 2010 Pwn2Own contest.
Even this year, after the release of new version, Google stays strong on Chrome and even announced a direct bounty of $20,000 prize for hacking Chrome (on the first of the contest’s three days), apart from the regular contest reward.
On a side note, Mozilla Firefox version 4 has entered its final beta stage and is expected to release by the end of this month.
