There are addons that can change the focus to the search bar, however I do not know what you want it to focus on. By default its the url bar:

Thanks for replaying. This doesn't solve my problem as you see from the attached screenshot.

I care to specify that I need the focus on the page, not the address bar nor the search bar.

Thanks cor-el. Unfortunately, same problem, it is not available.

You can find an older version for Firefox 40 on its versions page (latest release is for Firefox 41 and later).

I didn't think to watch for older versions. It worked. Thanks
