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. Jul 25, 2018 at 22:22

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

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.
