Tab Folders от Zoltan

If you have more than 50 tabs open, this app is for you!

This app is a tab organizer and a bookmark collection in one. It uses the most organic folder concept.

How to use:
Create folders, sub-folders, and store the shortcuts to your tabs in those. The shortcuts show the last screenshot of the page, so you can easily identify the page you need and select the already loaded tab.
If you close the tab later, the shortcut still remains in your folder, so you can easily reopen the pages. (bookmark function)

1. Install the add-on, and pin it, so it will be visible on the top at all times.
2. In the popup page of the add-on, create folders and sub-folders as needed.
3. Click on each of your tabs one by one and move the shortcut that appear in the popup page of the add-on (click on the scissors) into the desired folder.
4. After all your shortcuts are moved, drag an drop them to the desired position inside the folder.
5. Optional: Export the whole structure to a JSON file and keep this file in a safe place. You can import this on a new device or whenever you lose your settings.
