Downloading a file closes the source website. Once clicking on the download icon, the subject file appears and the source website closes. The file can be downloaded, but cannot return to the source website unless logging into the website again. The back arrow in upper left corner is not highlighted and cannot click on it. This is relatively new because it did not occur previously. Use to click on the download icon, the file would appear, download the file, hit back arrow and return to the website. Please help. Very time consuming and frustrating to have to keep logging into a website to get all needed downloads.
