Is there a way I can add a custom search URL to the Firefox search bar? e.g. I'd like to provide a URL such as, where Firefox replaces the %s with the content of the search box.

Both IE and Opera can do this, but I can't figure out how to set it up in Firefox.

adding a bookmark pointing to its query (with a shortcut on it) was the easiest (eg: bookmark ) – Guillaume Combot Dec 7 '15 at 7:41

Add keywords to the address bar:

For example, you can set up your browser to search for bread at by simply typing so bread into the omnibar.

Do this by right-clicking on the search bar on the website you commonly search. You can do this for the Search field on any website.

Right click on the search bar


  1. Go to the site you want to use to search
  2. Right-Click on the search box you fill out on their page (not Firefox's)
  3. Select "Add a keyword"
  4. Enter the keyword to use when you want to search in that site (eg: "so")

I had no idea that existed... just added 'su' for this site! works great, good tip! – codeLes Jul 17 '09 at 19:40
I wish chrome had this. – Jed Daniels Sep 13 '10 at 20:53
@Jed Daniels Chrome does have it in the form of custom search engines - Options -> Manage Search Engines – Dan H Jul 3 '11 at 7:12
@DanH, yes, but the chrome functionality is frustratingly lacking compared to the firefox ability. For example, it only works with search engines that have the search terms in the URL, and you have no control over which searches get added. – Jed Daniels Jul 3 '11 at 23:01
+1 Wow, to my mind that makes the regular search bar obsolete. – Kazark Jan 11 '12 at 20:23

I'd like to provide a URL such as "" where Firefox replaces the %s with the content of the search box.

You can do this with Firefox! Add a bookmark with that URL, where %s is the search query, then simply set a keyword for the bookmark. You can then search using <key> <search term> in the address bar. For example, the bookmark with keyword g means you can type g stack overflow in the address bar to search Google for "stack overflow".

Alternatively, go to the site you want to search, right click in the search box and click "Add a keyword for this search".

This is simply awesome! One more reason to love firefox. – qed Oct 20 '13 at 16:49
I momentarily thought this doesn't work anymore, but then I noticed I had put the keyword in the "Tags" field. It's working now! – Ed Brannin Jun 26 '15 at 14:25

The Add to Search Bar extension lets you create a new search addon with just a right-click.

I use this for my custom Google Search Engine. – Leigh Riffel Jul 17 '09 at 19:18

Your best bet is to go to the Mycroft Project and search for an already made search engine plugin.

If you can't find one you can create your own on the submissions page. Full instructions are available.

It's as simple as right clicking in a search field.

The other advantage is that this process creates a bookmark for you. If you use something like XMarks to synchronize your bookmarks, you can access the same search functionality across all synchronised computers.

Unfortunately it doesn't seem to play nicely with the builtin Firefox Sync. – sourcejedi Apr 7 '13 at 11:49

Here is a nice tutorial for Firefox's QuickSearch feature:

Quick search in a nutshell, allows you to turn a typical routined web search process into a command line shortcut. For example, instead of going to to enter the search terms there, you can use “w mySearchTerm” from Firefox’s address bar.

There are only a few steps you'll have to take:

  1. Right click on the search input field on the web page which provides the search form
  2. Choose "Add a keyword for this search."
  3. Give the custom search a name, you'll later use for searching (example: "mysrch" or a single letter)
  4. Search by inserting "mysrch yourSearchTerm." in Firefox's address bar.

Instead of creating it manually you can use a service like which provides an online form to generate your custom search plugin.

  1. Search for the word "TEST" in the search engine of your choice and copy/paste the resulting url to the form. eg.

  2. Fill out remaining info / click "create plugin"

  3. Click "Install" which appears above the form. The plugin will be added to your search bar.

I believe he's referring to keyword.URL in Firefox's about:config page.

In Firefox's address bar type about:config, then search for keyword.URL and replace its contents with "", for example.

You can also make complex searches with multiple parameters, here’s how.

For instance, imagine you have a two field search like this fictious example :


You can make a new search like :


Then you can directly search for : mm david bowie,ziggy startdust

I choose “,” as separator but it’s just an example. It’s perfectible but you get the idea, anything is possible.

※ Notice that you have to use a tab that has already loaded any page as blank new tabs don’t have javascript engine ready, same limitation in Opera 12. Only in Chromium that it is possible also in blank new tabs.
