FF WON'T OPEN. SAYS IT'S "NOT SUPPORTED ON THIS SYSTEM" USED TO WORK JUST FINE.

Icon has disappeared from dock, notice says "Firefox is not supported on this system", icon in Applications folder now has a circle and slant line through it. What happened? I tried to re-install it and got the same result. Am running OS 10.4.11

The last release from Mozilla that works on the old 10.4 was Firefox 3.6.18. As of Firefox 4.0 and newer a Intel Mac and OSX 10.5 and newer is required for it to run.

However since you are using a PPC Mac there is a third-party option at http://www.floodgap.com/software/tenfourfox/

Thanks! I thought it might be something Intel related. I have 3computers, 2 are Intel, this is not but still works for lots of things so I keep it. And I keep forgetting its limitations. You've solved it and Thank You.
