Firefox 13.0 is out
...and there are some internal changes you may not like....they changed the auto scrolling and what "shows" when u click New Tab (which now shows thumbs of recently visited pages)
If you want them "back to normal" just type: about:confiig in your address bar and change things like this:
1. Change: browser.newtab.url ...to: about:blank
...and make sure: browser.newtabpage.enabled ...is set to: true.
2. set: general.smoothScroll.mouseWheel.durationMaxMS and general.smoothScroll.mouseWheel.durationMinMS ...to: 150, and the Lag feeling will be gone.
/edit
You can just copy paste these listings, above, in the search bar at the top of the about:config page to find them..
you can just click the hide new tab page button in the right top corner of the new tab ^^
