Search sites directly using Firefox's “add keyword” feature

You probably use a search engine to navigate the Internet. However, you might not know that Firefox allows you to use bookmarks and the “add keyword” feature to directly search any website that has an input field. This provides a modest privacy enhancement since you're cutting out the middleman (your default search engine) and it saves time to boot.

Let's take Wiktionary as an example, a multilingual dictionary.

Navigate to Wiktionary and right click Wiktionary's input field. A menu should pop up.

A menu is displayed with the "Add a Keyword for this Search"
option
highlighted.

Click the “Add a Keyword for this Search…” option. Firefox should now present you with a dialog box asking for the name of the bookmark, the folder to save the bookmark in, and a keyword (I chose wkt).

A dialog box that asks for the name of the bookmark, the folder to
save it in, and the
keyword.

If you were following along, you can now type in wkt (or whatever you chose as a keyword) into Firefox's search bar followed by a word and find its definition. If you don't have any ideas, figure out what the difference between somnambulism and funambulism is, and why the two probably wouldn't go well together.

You can search the ArchWiki, Wikipedia, or whatever you want in this fashion. In addition, keywords work with ordinary bookmarks too (for instance, awl is mapped to the “List of applications” ArchWiki entry on my computer). The main difference with regular bookmarks is that you don't type anything except the keyword since you're no longer performing a query.

I prefer the bookmark method over adding a site as a search engine for two reasons:

  1. Firefox doesn't present the “Add Search Engine” option as consistently as you'd expect.
  2. Using keywords minimizes mouse usage, which translates to searching faster.
