The message says it is not supported by this archetecture.
After downloading Firefox to my Mac 10.411 laptop the Firefox symbol shows a no symbol and when you try to open it you get the message that it is not supported by this architecture. What can I do to get Firefox on this computer?

Is that a PPC Mac?
For older Macs that aren't supported in Firefox 4 / 5 / 6, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .

Or use the older Firefox 3.6.22
