The Yahoo! Toolbar is a free application that works only with the Web browsers Firefox and Internet Explorer. The toolbar fits along the top of your browser window, usually below the main URL box. Functions include email previews, updated eBay listings and a range of add-ons. The toolbar also has a Yahoo! search box for quick Web searches without visiting a search engine homepage. Instructions for removing Yahoo! Toolbar differ slightly for Firefox and Internet Explorer.
Shut down any open Internet Explorer browser windows.
Click the Windows "Start" button, usually a round icon found in the bottom left corner of the screen. Select either "Control Panel" or "Settings" and then "Control Panel", depending on your Windows version.
Click the link for "Uninstall a Program" under the "Programs" icon or find the "Add/Remove Programs" icon and double click.
Find the Yahoo! Toolbar in the list of program names. Programs are usually listed alphabetically, so scroll to the bottom of the list if necessary. Select the toolbar and click the "Uninstall" button.
Find the "Tools" drop-down menu along the top left of the Firefox browser window. It's usually next to the "Help" menu.
Select "Add-ons" from the drop-down "Tools" menu. This will bring up another window that lists all of your current Firefox extensions.
Look for the Yahoo! Toolbar extension. You may have to scroll down to find it if you have lots of add-ons.
Click the Yahoo! Toolbar icon. Several buttons should appear. Click the "Uninstall" button. A confirmation prompt will appear. Click "Uninstall" in the prompt box to confirm that you want to remove the toolbar.
Close all dialogue boxes when the toolbar has finished uninstalling. Close the Firefox browser and restart to run Firefox without the Yahoo! Toolbar.
If the Yahoo! Toolbar still shows up on Internet Explorer after uninstalling, try restarting your machine.
