I'm, running WinXP Sp3. I downloaded 10.0.2 and installed it as an upgrade as I have done successfully with all other new versions. It installs, but when it tries to load I get the following error: Platform version '9.0.1' is not compatible with minVersion >= 10.0.2, maxVersion <=10.0.2. I then have to run Win Uninstall, and then reinstall 9.0.1 to be able to get back online.

If you use ZoneAlarm Extreme Security then disable Virtualization and reinstall Firefox.
