Google provides a Chrome extension for returning the backspace function
Are you one of the Chrome users who received the latest update and just wondered what happened to the previous page shortcut a.k.a. the backspace key? It’s pretty useful, isn’t it? We miss it and a lot do, so Google themselves provided an extension for its browser to bring back the said feature.
The Chrome extension is called Go Back With Backspace and it’s straightforward to what it does if installed on your browser. The description says, “Many people lost their progress while working online by accidentally pressing backspace and leaving a page — so we removed the feature from Chrome, and created this extension for those who prefer the old behavior.” It simply explains why Google opted to remove the feature with the Chrome 52 version.
You may download the extension through the Google Web Store here and install. But, keep in mind that the extension doesn’t restore backspace on certain special pages like the Settings and Extensions panel.
