Hey per.billing,

There are a lot of benefits to running the latest version of Firefox. You might want to consider running the older version on on a USB Stick with PortableApps. That way you'll still be able to run the latest version for your day to day activities.

If you still want to roll back to a previous version of Firefox, just take a look at the Knowledge Base article Install an older version of Firefox.

Hopefully this helps!
