Leopard owners, it might be time for you to update your operating system. It's four years old, and companies, including Apple, are no longer supporting it. Earlier this year, 1Password dropped support for OS X 10.5 Leopard, and now Mozilla may do the same with Firefox.
Mozilla engineering manager Josh Aas proposed ending support for OS X Leopard in six months. It lets Mozilla address any final bug or security fixes and gives Leopard owners time to upgrade if they want. Leopard owners don't have to upgrade as the current version of Firefox will continue to work. They just won't receive any supplemental security fixes or enhancements to the browser.
If you want to upgrade your system, we are publishing a series of Holiday Gift Guides that'll help you choose the right Mac and all the accessories to go along with it. Apple also recently upgraded its Migration Assistant App to support a move from Leopard to Lion. It's free, and it'll make sure your apps and data make the transition successfully.
