Steps to reproduce the problem:
1. The backspace button used to be the button to return back to previous page for almost all users for as long as they have used computers/laptops. You can't just remove that option!! It's annoying and makes a very bad user experience, as if Google Chrome don't care what the users need. 

2. I understand your prospective for this change but I'd rather believe that you know that the user prospective is far more important & is the main thing because the user is one you create your programs for and make the changes to make it better not annoying!!

What is the expected behavior?
You can let the backspace button work in all pages as it was except for the forms for example or pages where people fill information.

If that suggestion is not possible then at least let there be an option either in settings or in Chrome flags for whoever wants to use that option to revert back to it. This way you're giving the choice to use or not use the backspace.

What went wrong?
The backspace has stopped working to go back to the previous page.

Did this work before? Yes
