For users who miss the old backspace navigation in Google Chrome, the 'Go Back With Backspace' extension is a simple solution. This extension re-enables the backspace key as a back navigation button, except when writing text. It was created by Google Ireland, Ltd., and updated to Manifest V3 in version 3.0.
The extension requires certain permissions to capture the backspace key on every page and to detect when it has been re-enabled to install its code into already open tabs. It doesn't modify or use your data in any other way.
While this extension can't restore backspace functionality on special pages like 'chrome://' pages, it works on most regular web pages. Users need to reload already open tabs for the extension to take effect.
To use 'Go Back With Backspace,' simply install it from the Chrome Web Store. The extension doesn't have a user interface or settings; it works automatically after installation.
