To permanently delete the Yahoo Mail upgrade prompt, log into your Yahoo Mail account and look for the upgrade notification. If it appears, click on the "X" or "Close" button to dismiss it. To prevent future prompts, consider adjusting your Yahoo Mail settings or using a different browser if cookies are causing the prompt to reappear. Additionally, keeping your browser updated can help minimize such notifications.
Yahoo mail only auto deletes the trash folder and there is no way to turn this off. The trash folder is emptied every couple of days.
Right click on the folder you want to delete. Read the options you want to do with that folder. Then, there should be a button that says "Delete Folder". Click on that and it will delete it.
Login with your username and password then follow the prompts at the bottom of the next page.
