My wife works with a MAC computer version OX3.0.9 using Firefox 2. Firefox asks her to update to a more recent Firefox program (for security reasons and new features) but it appears that Firefox 3 will not operate on OX3.0.9. Is there any way to overcome this problem (or is Firefox telling us that this MAC is reduntant and must be thrown away?). If so, it's a pity. Had the same problem with a new Google Earth program. Look forward to hearing from you and thank in anticipation. Edward Bent
