If I go to a website offering dictionary features, e.g. dictionary.com, I can easily add this search engine to Firefox using the search bar.

enter image description here

Say that I'm using Firefox without the search bar. How can I add a search engine using the address bar?

There's no option in the address bar for it as far as I can see; to add this search engine I changed preferences, added the search engine, then removed the search bar again.

    Currently the only apparent way is: 1) expose the search bar; 2) add an engine and pick it as default; 3) hide the search bar. I wonder if that's the way they have fun.

See the Mozilla article Search the web from the address bar :

When you type in the address bar and press Enter Return, Firefox takes you to search results using the search provider selected in the search bar.

You may also use smart keyword as described in How to search IMDB, Wikipedia and more from the address bar.

  • I want to add a search engine (to the list of search engines already in Firefox). The search bar allows us to easily do this (see image in question) but not the address bar. // What I want to know is if there is an easier way to add a new search engine without having to first show the search bar, then adding the search engine, and finally hiding the search bar again.

  • @Daniel , based upon the official Mozilla references that Harrymc cited, I'm afraid that the simple answer is "no." That being said, I would assume that you wouldn't be adding search engines too often, so hopefully the minor inconvenience of utilizing this workaround is rather rare.

    You may use the smart keyword mechanism : For example define "q" as the keyword for the search engine, then query by "q my-query" in the address bar.

There is now an option on the page action menu to add a search engine. This is available from Firefox 61 onwards.

enter image description here

From the release notes of Firefox 61.0:

Convenient access to more search engines: You can now add search engines to the address bar “Search with” tool from the page action menu when on a webpage that provides an OpenSearch plugin

    Now you just have to right-click on the address bar to see that option.
