Does the new FireFox 4 work with OSX 10.5? I ask this because read in an article on Mac Rumors 22nd March 2011 that it does and I quote "Firefox 4.0 is of course a free download, with the Mac version requiring a minimum of Mac OS X 10.5 Leopard Firefox 4.0 is of course a free download, with the Mac version requiring a minimum of Mac OS X 10.5 Leopard". Is this information correct?

Yes, it will work on OSX 10.5.8, but only with Intel processors.

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