+
+Re-enables backspace as a back button.
+
+Re-enables the backspace key as a back button, without affecting its use when
+you're writing text.
+
+Before Chrome version 52, if you weren't writing in a text field, the
+backspace key navigated back in your tab history. People who prefer that
+behavior can install this extension to restore it in Chrome 52 and later.
+
+Note that this extension can't restore backspace on certain special pages, for
+example any of the "chrome://" pages such as Settings or Extensions. This is
+an intentional limitation of the extension system in Chrome.
+
+About the "all sites" permission: In order to capture backspace on every page,
+the extension needs to install a little piece of code on each one. It does
+nothing else with the the page, its information, or your typing.
