Having Firefox recognize search field

[peteruithoven]

On Firefox, on most websites, it's possible to right click the search field and select "Add a Keyword for this search". Sites like IMDB, Youtube, Github etc.

This enables me to more start typing a search term right from my url bar:

I think this could be enabled by:

1. Allowing searching using a query parameter (?q=searchterm). (I understand this is a big ask) (Search using a query parameter #40)
2. Adding a <form> element around the input field. This will make Firefox recognize it as a search.
3. Giving the input the name of the query argument name="q" for example.

Interesting, I can look into it for the 0,5,0 release.
