It used to be possible to create bookmarklets in Firefox that accepted parameters.

For example, you could create a bookmarklet to open superuser.com and search for a term. You could then assign the keyword super to launch the bookmarklet. Then, if you entered super firefox into Firefox's address bar, it would perform a search on superuser.com for the term firefox.

In current Firefox versions (61-63), I can no longer find a way to do this. Is it still possible?

    Regrettably, I find most old bookmarklets no longer work since v. 57, or possibly before, so I hope there is some answer, too. – DrMoishe Pippik Jul 25 '18 at 22:22

Yes, right-click a search box and select "Add a Keyword for this Search...": https://support.mozilla.org/en-US/kb/how-search-from-address-bar

The keyword you configure for the search box in the dialog that appears will function the same as the bookmarklet described in the question.


Just tried on Firefox 61 (Win10/64bit) and it worked exactly as you described. The URL just need a "%s" where the search term would go. Example:

Bookmark URL:


super keyboard error
