When prompted and encouraged by you yesterday I downloaded Firefox 4. However it was not possible to use it because it came up with the message that It "is not supported by this architecture" I then found that I could not run my earlier version of Firefox 3.6.16. So I had to delete all firefox versions, and redownload version 3.6.16 losing various previous settings in the process. I am now using the old version once more quite successfully but I am concerned that you will not be supporting it for very long

Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox

thank you Tony, the further question I want to put to Firefox is why they are offering version 4 to everyone without making it clear that one needs at least OS X 10.5 and an intel MAC. It would have saved me a heck of a lot of work. Nowhere on the Firefox site can I find any avenue for actually contacting anyone at Firefox.
