After the seed phrase information is safely stored, the browser cache should be cleared, and the browser process exited, to remove all traces of sensitive data from the browser and computer memory. If you used a temporary operating environment such as Tails Linux, then clearing browser memory is not strictly necessary, since nothing from the entire operating environment is written to disk, and everything is removed from memory when the instance is stopped. If you used a browser in an offline, non-temporary operating system, documentation for the specific browser version used should be consulted to ensure completion of all steps needed to clear the cache and history for both the rendered window and the console used to run the script. For Chrome, this may include choosing the menu item "More Tools," "Clear Browsing Data," "All Time," and additionally selecting "Cookies and Site Data," "Cached Images and Files," and then clicking "Clear Data." To clear console history in Chrome, the console window offers a context menu to "Clear Console History." For Firefox, this may include choosing the menu item "Privacy and Security," "Cookies and Site Data," checking all available boxes, and then clicking the "Clear" button. To clear console history in Firefox, run the "clearhistory()" command.
