Last Updated: January 17, 2015 If you’re using OS X 10.5.8 Leopard then you can still which works on 10.5.8. However, we strongly recommend you upgrade to at least OS X 10.6 Snow Leopard or higher as Firefox 16 is no longer updated by Mozilla and therefore not secure anymore. Note that this only works if you’re using an Intel Mac – if you’re still using OS X 10.5 or 10.4 on a PowerPC Mac, then we recommend. In this case you’ll need Firefox 3.6 for Mac which was the last one to support PPC Macs but is even older and more vulnerable than Firefox 16. In this article, we look at the risks and problems of using Firefox 16 and highlight what your options are.
WARNING: Firefox For 10.5.8 Is Not Safe! Since Firefox 17 until the latest version of Firefox, you need at least OS X 10.6 Snow Leopard or higher to run the browser safely and efficiently on your Mac. We emphasize that using Firefox 16 is not a good idea because it is no longer updated or supported by Mozilla leaving it vulnerable to attack, malware, spyware and other online threats.

I've changed the OS 10.6.8 'Snow Leopard' language to French. This configuration with a highly 'tweaked' FireFox 8.0.2 browser in English (updated from FireFox 10.0.1) worked a treat, and the laptop ran splendidly. Receipt for mac and cheese. Extract program from computer. Mozilla will end support for Firefox on OS X 10.6, 10.7, and 10.8 in August, 2016. At that time, Firefox will continue to function on these platforms but will no longer receive new feature or security updates.
