After upgrading to firefox 8, I can't use many of the functions on my schools website like opening the textbook and sending emails. I spoke the school's tech. support & they informed me that my version of firefox was not compatible with their system. So, how do I install a previous version of firefox (firefox 6 to be exact)?

You can download Firefox 6.0.2 for Mac OS X 10.5 from ftp://ftp.mozilla.org/pub/firefox/releases/6.0.2/

Backup your Profiles folder before new installation.


edit: replaced random third-party download site link.
