This is a very helpful addon, saved lots of effort. Pros:
Cursor was automatically placed at most of the first places for eg: serach here or at the Goggle's home page. Using this addon will definetly reduce your mose clicks and movement.
Cons: Only drawback I found till now, the cursor isn't automatically placed at Re-Captcha's text area if Re-Captcha is at first place, for eg: you need to fill Re-Captcha first to visit some site or by some means you have hiddedn all elements except Re-Captcha.
Hope this minor issue will be fixed in the next update.
