I understand that Firefox 3.6 is no longer supported so I have tried to update to the current 14.0.1 from the Mozilla site. It downloads fine but when I try to install it I get the popup window stating: "not supported on this architecture". I have a Mac G5 running OS 10.5.8. Any ideas or is there a way to get a Firefox upgrade for OS 10.5? Thanks.

Sorry, PPC architecture isn't supported in Firefox 4+ versions.


For older Macs that aren't supported in the Firefox 4+ versions, try TenFourFox for PowerPC's running  Mac 10.4.11 & 10.5.8 .
