The Firefox QuantumBar (formerly AwesomeBar, or just address bar) is surprisingly capable. There's a lot you can do with it to quickly navigate through your browser. It's one of the things which makes Firefox so comfy to me.
I like to be as quick as possible without leaving the keyboard. For this, I use scope characters, bookmark keywords, and DuckDuckGo bangs. In this article I'll go through these features and hope to show you something new, no add-ons required.
