I am trying to found out what the system requirements are for 4.0 of Firefox. I ask this because I am currently running Firefox 3.6 on 11.3 OpenSUSE Linux. I am considering an OS upgrade. I built a LiveCD to test the new OS before installing and when I try running Firefox it crashes. It is apparently 4.0 beta or something. Nowhere can I find a simple list of system requirements for Firefox. Current hardware: AMD Athlon 1.6 GHz, 512 MB mem, USB 1.0 ( an older system )
