I want to enable or use Backspace to switch back to previous page that I visited previously in the Firefox browser on Ubuntu. For example, if I am using any browser on Windows, I can use Backspace instead of back button in browser to go to previously visited page.

  • Which browser are you talking about? By the way, this is a browser issue, not an OS issue.

Type about:config in the address bar of Firefox and search for browser.backspace_action. Change its value from 2 to 0 and now you can use Backspace to go back in history.

It's not an OS issue, but this way you will get it to work

Open your Mozilla Firefox browser, and in the address bar, type about:config. Then search for browser:backspace_action. Since the entries are in alphabetical order, it's essy to look for it. When you have found it, double click on it and change its value to 0 from 2. That's it.

You will find these steps in detail in the following article (see link)

    I don't know if there have been changes in Firefox, but nowadays the setting is browser.backspace_action. Then, I had to change the value to 0, not 2.

  • I confirm that changing the setting from 2 to 0 was also the way for me (Ubuntu 20.04, Firefox 84.0) Dec 26, 2020 at 13:06
