We I go to the website to enter grades, I get this "WARNING: Your browser is not supported. Click here for more information" and it just tells me this " Supported browsers are IE7 IE8 or 9 You must have Compatibility View enabled for this site Firefox 3 - 8 on PC or Mac Safari 5 on Mac"

I need to go back to the 8 version. How can I do that?

Hey Qjenn,

There are a lot of benefits to running the latest version of Firefox. You might want to consider running the older version 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!
