I don't like Firefox 7, how do I revert to the previous version? System restore doesn't work.

Question

With Firefox 7 my computer is slower to boot up and shut down. When typing the website I want in the address bar the old firefox took me straight to the site now it takes me to Google. I'd like to revert to the previous version of Firefox. I have tried using system restore but it doesn't work. I'm using windows XP. Can anyone help?

Starting with the release of Firefox 7, the previous versions of Firefox (4.0.x, 5.0.x and 6.0.x) are no longer maintained with Security and Stability updates. Firefox 3.6 is the last previous Firefox version that is still being maintained.
Firefox versions 4.0.x 5.0.x 6.0.x contain Security vulnerabilities that are known and could be exploited by some websites to gain unauthorized access to information or to disrupt critical processing. Only the Latest version 7.0.1 and an Older version 3.6.23 of Firefox are secure against these known vulnerabilities.
