When I'm browsing, I don't want links in the top bar to tempt me to context switch, so my bookmark bar is off and my left hand rests next to my keyboard. If I want to navigate to a site, I either type in the URL if I remember, or hit Ctrl+B to pull up my bookmarks. I put the bar on the right hand side so it doesn't move the starting position of page text, and select using topic based folders (usually within a top-level folder). The whole process is very comfortable. Often I'll be lazier than that and just prefix with a * to directly pull up the link via search.
Its honestly so far ahead of everything else, I feel like I'm on another planet when people say they prefer Chrome for productivity.
