What's different about the Awesome Bar from Chrome? IIRC Chrome had the unified search/URL bar before Firefox did, and I don't remember it being very different from Firefox's implementation. If anything, I remember it being easier to add search engines in Chrome (unless it's gotten worse in the past few years since I switched to Firefox).
Am I missing out on cool features of the URL bar in Firefox?
Edit: made my question more specific
Not sure if chrome has an equivalent but FF bar allows limiting results, e.g. adding a single % in the bar will search tabs, ^ history, * bookmarks, (+ searchs tagged bookmarks? there's no shiny icon)...
You can start typing words that were in either the title or the URL of some thing you vaguely remember visiting last month, or last year, and the Awesome Bar will reliably surface it for you. I hardly even use bookmarks; I just count on the Awesome Bar finding everything for me. If I had to choose between it and uBlock Origin, I wouldn't even have to think twice. Ads I can deal with, if I have to. I've been outsourcing my memory for the web to the Awesome Bar for decades. It's part of my brain.
Firefox doesn't report every keystroke put into the Awesome bar back to Mozilla, AFAIK.
I'm sure it varies from person to person, but I find it very frustrating to use Chrome's equivalent of the "Awesome Bar" when I'm forced to (eg work computer); Firefox just seems to do a much better job of surfacing open tabs (yes, I'm a tab hoarder), bookmarks, history, etc while Chrome seems like it'll surface some dubiously relevant options and try to railroad you into search. Even when I know I have a tab open and I know the domain name or a substantial chunk of the title it is legitimately rare for Chrome to offer to switch me to that tab, and often times it will surface one or two tabs that seem utterly unrelated. Bafflingly bad performance from what used to be a search company.
Among other things, it's less about searching the web, and more about reliably surfacing your history and bookmarks and already open tabs.
