Brings newly created tabs of bookmarked links to the foreground.
Middle-clicking (or Ctrl-clicking) a bookmark link will open a new tab in the foreground. A middle-click of an unbookmarked link will open in the background.
This affects any new tab for a link that you have bookmarked, not just when clicking in your bookmarks.
1.1.1: Fixed to work in Chrome 79 (which moved the URL string).
