I would still second this . . . .
My workplace still has some legacy web apps that don't display well in all browsers. There are some URLs I prefer to visit in chrome, some in safari, and some in Firefox.
Regardless of which browser is preferential -- I tend to always start in Alfred, it's habit.
Right now, if a URL is detected, Alfred gives me the option to "Open the typed URL". It would be *awesome* if, instead, the default option was to open the URL in the default browser -- but other selections offered the ability to open it in other installed browsers.
Bonus points would be if that 1password fills had the same ability
