I need to use an older version of FireFox for the Mac (3.0) to be compatible with another program; how can I get it?

My company uses SalesForce CRM and recently changed wholesale to Macs. Unfortunately, certain functions in SalesForce are not compatible with the current version of Safari or any version of FireFox newer than 3.0 and we need to be able to use those functions. How can I download that version for the Mac?

There is also a portable Firefox 3.0 version via this link:

It can take some time before the download starts.
