This is my approach: address-bar autocomplete only uses bookmarks as suggestions (well, and open tabs). I almost never open my bookmarks, nor feel the need to organize them. I can just type two or three letters (not necessarily the first few) to directly identify the (bookmarked) site that I want to go to.

Obviously that means I'm using split url/search fields in the address bar, or that wouldn't work. I also heavily use Firefox' keyword search to avoid doing a round-trip through a search engine if I already know which site I want to search, mostly using the same prefixes that DDG uses, so I don't need to adjust too much if I need to use a different computer.

This sounds pretty good. Thanks.

I have actually already split my address and search fields too, for a different reason. I got aggrevated with having the local machine names on my lan perform a public search, even though my local dns is configured to use only my opnsense router, which does resolve the local names correctly. Splitting off the search box makes the local names always do only what DNS says, and so I get my 3d printer instead of search results for it's name.

For that particular problem, going to "truenas" or "unifi" etc on my lan, the bookmarks are actually more convenient in nmost cases I have to admit! Especially with half of the services needing some special port number like unifi and jellyfin etc.
