Scroll Up Folder per Bruce Bujon (Perfect Slayer)

Goes up a folder of a website.

The last version was written from scratch to use the WebExtensions API for the future versions of Firefox. Some features may still be missing but please don't post bad review because you miss it. Instead, come to discuss about which one you would like to see added next!

Usage: Clicking on the toolbar icon opens panel with all folders. The highlighted row is your current address.
Click on any folder to load it in the current tab.

Shortcuts: Anytime while browsing, you could use the following shortcuts:

• Alt+Shift+Up to navigate to the upper folder,
• Alt+Up to navigate to the next folder up,
• Alt+Down to navigate to the next deeper folder,
• Alt+Shift+Down to navigate to the deepest folder.
