Problems after upgrading Firefox are generally not caused by the new version itself, but rather the upgrade process. Installing a previous version will not help for most problems. To get help, see:
- Common questions after upgrading from Firefox 3.6
- Fix problems connecting to websites after updating Firefox
Other problems can be solved by creating a new profile.
I still want to downgrade — where can I get the previous version?
