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.

Does not support "javascript:" bookmarks

Simple and convenient.
Features request:
1. Processing special addresses (javascript: , about:)
2. Processing folders - show content and next Alt+1, Alt+2, ... , Alt+9 start bookmark

It's simple and it works.

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.

How should i do when i want to access after tenth bookmark?

Works good on windows 10, ff 57 (64-bit). It would be nice to have the opportunity to change "alt" to "ctrl" though. Thanks!

Work well in ff 57 on Linux, Ubuntu 17.04.
Thank you!

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