Useful. Thank you.

A minor inconvenience is that Ctrl+T to open a new tab must be used first, otherwise the shortcut opens in the active tab.

Would also like to have about:logins, et al, work as bookmarks 1-9, but they don't. About:profiles and about:restartrequired are my go to shortcuts to restart Firefox with only two mouse clicks. I've found no other shortcut for this.

Works perfect (just like the way chrome does it)
Its simple, small, clean, and but I have one nitpick - when I click on a bookmark with the scroll-wheel to open that bookmark in another tab, I don't want to switch over to that tab immediately. I want it to load in the background while I continue on the tab I'm already on.

Thanks for making this one.

It works.
Alt+1 for first bookmark,
Alt+4 = fourth bookmark, etc...
