I have a MacBook pro with Mac OS X 10.4.11 I have used firefox for years happily. I was having problems with vimeo and they told me to upgrade firefox. So I did. to the new version of firefox. Firefox let me download it and prompted me to upgrade. But now that I have done so, I cannot load the new firefox because it says my version of OS X is outdated! This is frustrating. I cannot get into firefox, and have thus lost all my very important bookmarks etc. This is bad. Upgrading my OS is not an option as it will require a huge hassle (archive and install etc). I wish firefox had not allowed me to downlaod the new version, a this has now meant I cannot use firefox and have lost valuable data stored in my old verssion. Is there a way to download the old version of firefox again, the one that works on 10.4.11? Thanks, [email protected]
