## Description

New Hackbar is a webextension-based sitebar designed specifically to assist penetration testers in performing manual web security testing directly inside their browsers. It serves as a modern alternative to the original XUL-based Hackbar, ensuring continued compatibility with Firefox versions 57 (Quantum) and later.

Featuring most core functions of the original Hackbar, New Hackbar provides an intuitive interface accessible from either the left or right sidebar to conform with Firefox's policies. Key functionalities include URL loading, execution commands, and URL splitting, with keyboard shortcuts such as F9 to toggle the sidebar and combinations like Alt + A or Control + Z for quick actions.
