For Opera Browser:
This trick doesn’t work in Opera as it doesn’t support changing the user agent to specific versions of Internet Explorer like other browsers.
For Internet Explorer:
If you’re using Internet Explorer 7, then I’m sure you’re still viewsing your profile with the old profile layout but if you’re using Internet Explorer 8 or later versions, you only need to do some compatibility settings so your browser tries getting you that old facebook profile layout by viewing facebook as Internet Explorer 7.
1 . Go to your facebook profile.
2 . Click on Tools > Compatibility View Settings.
3 . Fill in facebook.com, click on “Add” and then “Close”.

4 . Refresh your profile page to see if it works.
Like I mentioned earlier, this tweak only switches the your profile back to the old layout for you only. Visitors to your profile still see your timeline. There’s no sure know to totally disable facebook timeline for now, you can only try to limit or hide it or try deleting all your old posts.
