In Chrome, head to Settings, then pick Show advanced settings, and then Clear browsing data. In Firefox, you can find the setting under Options, then Advanced and Network. For Opera, choose Settings then Privacy & security, and click Clear browsing data. In Microsoft Edge, open Settings, then click the Choose what to clear button under Clear browsing data.
