My advice is to install the Firefox Portable version that you need on your computer, and use that installation only for Blackboard. Continue to use 3.6.x for all other web browsing. The Portable version won't affect the official version at all. FP 3.0.x is here: http://portableapps.com/apps/internet/firefox_portable/localization#legacy FP 2.0.0.20 is here: Firefox, P.E. Legacy/Firefox_Portable_2.0.0.20_en-us.paf.exe

This page shows that Firefox 3.5 is supported as well: http://onlinecci.com/index.learn?action=Technical

Supported versions:(Mozilla Firefox) * Mozilla Firefox 2.0 * Mozilla Firefox 3.5

So try the portable Firefox 3.5 version. See "Legacy Versions" http://portableapps.com/apps/internet/browsers/portable_firefox
