I did not find the "Backup" or "Export Settings" function, I hope to add it, which will greatly enhance its convenience, thank you

This add on is useful to behave a desktop browser like an android phone, particularly on sites like instagram so that I can upload photos from my disk drive. Unfortunately, you are unable to tag people, set place, and upload multiple photos.
