Gets the Job Done Rated 5 out of 5 stars

QuickMark does exactly what it needs to do. At the click of a button or a simple keyboard shortcut, it saves a bookmark quickly and easily. The add-on's strongest feature is in the keyboard shortcuts, for minimalist users like me to bookmark things without needing to move the mouse.

One issue I noticed is that the shortcut CTRL+D fails to create a folder like it should. If this could be fixed, it would be a very useful feature.

It would also be great if it were possible to customize the keyboard shortcuts, just in case there are conflicts with other add-ons or web applications. Other than that, it's a solid time-saver. I don't know how I survived without it.

* EDIT 2/7/16 : After a simple browser reset, my navigation and folder-creating issues cleared up! Sorry about the confusion. I've revised my rating accordingly. Thanks for the response! :)

This review is for a previous version of the add-on (1.2.9). 

Something must be amiss. It seems that all keyboard inputs are not working for you in the folder menu? The folders should actually be navigable through the arrow keys or by simple typing the letters of the folder you would like to select.

A previous user had this problem as well. In her case she had an add-on installed that prevented the folder menu from getting the focus it required for the keyboard input. So you can look into that.

If you want further support you can send me some information about your particular setup, email me or leave a post in the support thread:

But as far as I can tell, everything is working.

And thanks for the feedback.
