Essential for Linux build Puntuado con 5 de 5 estrellas

I was getting really aggravated with the way the previous search 'stuck' in the search bar in the Firefox Linux build, forcing me to clear it before typing a new search.
This add-on may not have been created with the purpose of fixing that annoyance, but it definitley does the job.
And it's perfect for its intended purpose as well. Great idea; smooth and lightweight implementation.
