Found others same problem Found link to old version in this forum. Downloaded it. Thank you. Would like to know how long it will be supported. Can't afford a new computer with an Intel chip yet.

How do I return to the old FF3 version? I have a FF icon with a line through it and can do nothing with it, nor can I find the old FF3 file...... Is there step by step instructions? I've never downloaded something that I've not been able to correct. But this has me perplexed... HELP!!!  :-)

I certainly wish there was a warning that FF 4 is not compatible with Mac PowerPC processors.  My desktop Mac G5 is my little workhorse and I also cannot purchase a new Mac yet.

Yes, a big orange warning would have been helpful. Here is the link for 3.6.16 for anyone else with this problem:

My G4 is not compatible with my video camera, either; one of many cascading examples why I'm feeling "old". Cheers and best wishes to those of us with not-flat 20 year old TVs, and whose turn-table record players still work.
