Frank has a question about Yahoo: “Is it possible to delete contents of Yahoo dropdown menu? 8/5-16.”
I’m not precisely sure what you mean by the Yahoo drop-down menu. If you mean the drop-down menu you see when you select settings in Yahoo mail, the answer is no.
But I suspect that you’re talking about either using Yahoo! search or the Yahoo web portal as a start page.
To clear that, choose the settings gear icon and select Preferences from the menu.
From here you can turn off your search history. You can also adjust the privacy settings of the browser you’re using to tell it not to save search history and to delete your history. That process will vary depending on the browser.
