My Mac X10.5.8 PCG5. Can't open Firefox 4 'not supported on this architecture' why not?
When I tried to open Firefox 4 a dialogue box opened stating "Can't open the application Firefox because it is not supported on this architecture"

For older Macs that aren't supported in Firefox 4.0, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .
