Jumper

This extension allows you to quickly jump between your favorite pages. You define a key sequence to launch the JUMPER, and then assign the pages you visit frequently to successive letters of the alphabet (A-Z). This way, you can literally jump between frequently visited websites with just 2-3 keystrokes. Think this extension can have a positive impact on your productivity and save you a lot of time. It’s something for people who like working with the keyboard and keyboard shortcuts.
