Is Firefox 3.6 still safe for business use? I understand the general reasoning around upgrades, however I need specific and definitive reasons supporting if/why a business should not downgrade form Firefox 9.1 to Firefox 3.6 (if there are any reasons). What would help is to know if/what vulnerabilities exist in Firefox 3.6 (they are not clearly listed on your known issues pages), and if/how long Firefox 3.6 will be supported by Mozilla. Thank you.

Firefox 3.6 is still getting security updates, 3.6.26 is scheduled to be released on Jan 31. Support will probably end on April 24, twelve weeks after the Firefox 10 ESR version is released to enterprise users.
