Good Start Rated 3 out of 5 stars

A good start to the plugin! I happen to use the alt + left & alt + right to quickly fly through my browser history. It would be nice if the plugin were able to either allow the user to customize the keys or use key combos that aren't existing defaults.

This review is for a previous version of the add-on (1.3.1-signed). 

Thank you for your interest in the extension and for taking time to write a review!
Adding the ability to customize the keyboard shortcuts are definitely on the todo list!
