Looking at those old screenshots shows me how much the current autocomplete has regressed. The suggestions used to be so much better since it was a literal text search across titles and URLs. I remember you could configure how many results were displayed, I always set it to the max.

The 2-line rich display was awesome for scanning URLs too. The "URL after the title" we have now makes it impossible to do that.

Edit: Fixed most of these annoyances with this: https://www.userchrome.org/megabar-styling-firefox-address-b...
