Mozilla has revealed that they are aiming to retire the Firefox 2.x release by the end of the current year.
The developers have plans to issue just two more security updates for Firefox 2 in the coming months.
A Mozilla representative said that they expect the last release of Firefox 2 to be Firefox 18.104.22.168.
Firefox 22.214.171.124 is currently the latest version available in Firefox 2 series.
Mozilla added that majority of the users upgraded their installations to the Firefox 3 release when they released the auto-update earlier this year.
