I have a Mac Power PC G5 (i.e. pre Intel) and I am using OSX 10.5.8. My current Firefox is 3.6.24 and they tell I should upgrade, I guess to FF 4, but tech. spec. recommends Mac Intel. Is a Power PC compatible with FF4? Thanks

No, Firefox 3.6.x. is the last version of Firefox from Mozilla for PPC Mac's.

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