Awesome, does exactly as described! Rated 5 out of 5 stars
Easily the best new tab homepage add-on out there. Key feature: it puts the cursor in the on the web page vs. address bar (very useful if your homepage is a certain search engine). Great that it doesn't suffer compatibility issues with constant Firefox updates, unlike older new tab homepage add-ons.
@ComicOzzy: There's a main difference between adjust about:config and this add-on, the cursor placement.
