Disable Facebook Timeline 100% work

If you have got Facebook Timeline and want to change back to viewing the old style profile pages, or if you haven't got Timeline yet, but just want to view your friend's Timeline pages in the old style profile format, this guide is for you.
Currently, if you visit a Facebook Timeline page, with a browser that identifies itself as "Internet Explorer 7", you will be shown the old style profile page for that person, instead of their Timeline page. This is because Facebook haven't yet created a version of Timeline that works with IE7, and if their level of support for IE6 is anything to go by (no chat, no ticker and no timeline), they probably never will.
When you visit a website, your web browser sends it an identification code, known as the "User Agent", which lets the site know what web browser you are using. This method for disabling timeline works by changing your current browser's "User Agent" to IE7 and tricking Facebook into showing you the old style profile pages. One problem with this method, is some page formatting errors occur on profile pages/fan pages and group pages, in particular theres a big gap between the heading of the page and the actual content. You can fix this by installing the latest version of FB Purity, the web browser extension that cleans up your facebook experience.
