Backspace Enabler is a Mozilla Firefox add-on designed to restore the functionality of the Backspace key as a navigation shortcut. After Firefox 86 disabled this feature by default, Backspace Enabler provides a simple solution by allowing users to return to the previous page with a single key press. This add-on retains the original text deletion function of the Backspace key when the cursor is in a text field, ensuring that it does not interfere with typing tasks.

The installation of Backspace Enabler is straightforward, making it accessible for users looking to enhance their browsing experience. It effectively re-establishes the familiar navigation feature that many users relied upon, all while maintaining the integrity of text input. This add-on is a valuable tool for those who prefer keyboard shortcuts for navigation.
