For years I’ve had shortcuts in Firefox. In this example, I’ve long been able to type i thing in my URL-bar and it would immediately take me to a google image search for “thing”. In the past this was added by right-clicking “search” on some page and selecting “add a shortcut for this search”. At some point, though, that went away. The functionality is now hidden a little, and you solve it with bookmarks (which I also haven’t used in any form for years).
