Here an example (with r/DataHoarder old Reddit UI) after we changed our workflows, to improve amount of backup versions on Web Archive. Currently is not possible with Safari (our main browser) and other browsers too.
By installing such Chrome Extension you upload automatically all visited pages to Web Archive. You can install such extension on browser profiles that you don't use for business/finance or other important things.
There are some scripts you can try to install on other browsers, but don't work correctly. Another way is to install Autobookmarks and Archiveror, then you need to configure which website you want to store in WebArchive (this means to bookmarks too) and once done, all your bookmarks are automatically uploaded to WebArchive.
If you are using Chromium based browsers please help us to do the same with so many other websites too.
