Q: Use different search in "search box" that in "search bar" in Firefox Before the "search box" doesn't linked to "search bar". Then I can have a different searchs in each.
I want to be able to configure Firefox to have different searchs "search box" and "search bar".

A: You're quite late to the party. Mozilla removed the keyword.url about:config entry way back in Firefox 23.
According to this article written at that time, the Keyword Search add-on allows you to do what you want. The recent user comments show that it still works as of Firefox 38.0.1.
