- Rewritten to not require any extra permissions when using the "Open new tabs in the background" option.
- New minimum Firefox version: 91.0. Install v1.5.3 or v1.5.2 for older Firefox versions.

- Minor improvements to the preferences page.
- New minimum Firefox version: 77.0. Install v1.5.2 for older Firefox versions.

- The extension now relies on the built-in shortcut editor.
- Handle the optional permission better.
- Dark mode support.

The extension now uses optional permissions for the features that require the tabs permission.

There are two new shortcuts in this version:
- There is a shortcut to pop the current tab (or multiple highlighted tabs) out to a new window.
- There is a shortcut to open a blank new tab to the immediate right of the current tab (i.e. instead of all the way to the right).

Enjoy!

Make shortcut customizable. Add second shortcut to open the tab in a new window. You can configure and use both shortcuts at the same time.

Added option to open tab in background.

Removed context menu item as it is now built-in to Firefox 57.

A "Duplicate" item was added to the tab context menu (right-click menu).

Changed shortcut to Alt+Shift+D because Ctrl+Shift+D conflicts with "Bookmark all tabs". There is unfortunately no way to reassign this shortcut after installing.
