I have been using Firefox for several years on my iMAC G5, running MAC OS 10.5.8. This morning, Firefox won't open. Tried opening from the icon in the Applications folder, but still won't open. Safari opens without difficulty. Tried downloading Firefox again, thinking a file might have been corrupted, but new version is not compatible with my desktops hardware. Can I find a compatible version of Firefox? My NAV for MAC security software isn't interfering.
