I don't like Fjirefox 9.01. Please tell me how to uninstall it and install Firefox 4.

Hey Ray3Mond,

There are a lot of benefits to running the latest version of Firefox. You should consider leaving feedback for the developers so that they can continue to improve the product.

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!
