Saving data to a web browser may not work in the event of certain malfunctions. The best way to eliminate them in this case is to reinstall the program.
Check if your browser is responsive when you press keyboard shortcuts to save certain content. Try saving from the menu. If in both cases there were no changes, and besides, the desired option was also missing from the File menu, it is most likely that viruses that damaged the system files of your browser are to blame. In this case, you should use a complete reinstallation of the browser. Although it is possible to identify damaged or missing files and replace them later, in this case, the smooth operation of the browser is not guaranteed. Save bookmarks and other user data you need from the faulty browser, for example, logins and passwords of accounts of various Internet resources. Perform a complete uninstall of the browser from your computer, followed by clearing the Temporary Internet Files directory and browser directories in Program Files. Run the anti-virus database update and then run a full scan of your computer. Start the operating system registry editor (Start-Run-Regedit) and search for entries in its directories that contain the name of the browser you removed, and erase them manually. After a complete scan of your computer for viruses, download your browser from the developer's official website. Install the downloaded browser on your computer and configure it. Enter the logins and passwords you saved earlier, add the desired page addresses to bookmarks. Install an anti-virus system on your computer, which contains a network scanner in the list of components - this will help you avoid such problems in the future. Also, do not forget to periodically update the anti-virus database and perform a full scan of your computer.
