Yahoo has a feature that allows you to stay signed into the site for up to two weeks without having to enter your username and password every time you want to access your mail or other account features. This feature is convenient if using your home computer or one to which only you have access. However, if you enable the feature inadvertently on a public computer, others may be able to log in to your account and see private mails or data. Deleting Yahoo browser cookies disables the feature and forces you to enter a username and password on the next visit to the site.

Google Chrome

Step 1

Click the icon with three horizontal lines to the right of the Address bar and then select “Tools” on the drop-down menu. Click the “Clear Browsing Data” link on the slide-out menu.

Step 2

Click the “Obliterate the following items from” drop-down list and select “the beginning of time” option.

Step 3

Enable the “Clear Browsing History,” “Clear Download History,” “Delete Cookies and Other Site and Plug-in Data” and “Empty the Cache” options.

Step 4

Click the “Clear Browsing Data” button to delete the Yahoo cookies and others browsing data stored on the computer.

Close the Google Chrome browser and restart it.

Mozilla Firefox

Step 1

Press the “Ctrl-Shift-Delete” keys simultaneously to display the Clear Recent History window. Alternatively, click “Firefox,” “History” and then “Clear Recent History.”

Step 2

Enable the “Everything” option in the “Time Range to Clear” drop-down box. Click the down-arrow icon next to the “Details” label.

Step 3

Enable the “Browsing & Download History,” “Form & Search History,” “Cookies” and “Cache” options.

Step 4

Click the “Clear Now” button and wait for Firefox to delete all cookies and browsing data from the computer.

Close Firefox and restart it.

Internet Explorer

Step 1

Click the “Gear” icon and then select “Internet Options.”

Step 2

Click the “Delete” button under the Browsing History header on the General tab.

Close and restart Internet Explorer.


  • Deleting your browser’s cache and cookies can also help Yahoo login issues as well. For instance, if you enable the “Stay logged in for 2 weeks” or “Keep me signed in” option when you sign in to Yahoo and your browser continues to prompt you for a username and password each time you visit the site, the cookies on your computer may be corrupt or defective. Deleting the cookies forces the browser to download new ones when you revisit the Yahoo site and sign in.
  • Most browsers allow you to delete individual cookies as easily as removing all of them at once, but the process varies by browser. In Chrome, you can view cookies by selecting “Options,” “Under the Hood” and the clicking “Show Cookies.” In the Cookies window, select all of the entries with “” in the name, and click the “Remove” button. Opera has a similar feature in the Cookie Manager window that you can reach by clicking “Tools,” “Advanced” and then “Cookies.” To delete individual cookies in Firefox, first click “Firefox” and then click “Options.” In the Options window, click “Privacy” and then select “Use Custom Settings for History” in the “Firefox Will” drop-down list under the History label. Click the “Show Cookies” button, select a “” cookie and click “Remove Cookie.” Highlight and remove additional Yahoo cookies as needed until you remove them all. If you use Internet Explorer and want to remove only the cookies, first click the “gear icon” at the top of the browser window and then click “Internet Options” on the drop-down list. Click the “General” tab, “Settings” and then the “View Files” button. Highlight all of the files that begin with “cookie:” and have “yahoo” in the file name. Press the “Shift-Delete” keys to remove the cookies permanently from your computer.
