Yahoo! Pop-Up Blocker is only available for Yahoo! Toolbar 5.6 or newer for Internet Explorer. Pop-Up Blocker is enabled by default, however you can turn Pop-Up Blocker on and off using the Pop-Up Blocker menu ().

To check the status of Pop-Up Blocker:

1. Click the Pop-Up Blocker toolbar icon.
2. Look at the "Enable Pop-Up Blocker" line.
3. If there's a checkmark next to it, Pop-Up Blocker is enabled. Otherwise it's disabled.
4. You can also tell by the toolbar icon. It's yellow if enabled, and gray if disabled.

To turn Pop-Up Blocker on or off:

1. Click the Pop-Up Blocker menu.
2. Select "Enable Pop-Up Blocker".
3. If the checkmark was present, Pop-Up Blocker is now off. If the checkmark was not present, Pop-Up blocker is now enabled.

Please see "Pop-Up Blocker is blocking something I want to appear" if that's why you're interested in turning off Pop-Up Blocker.

Note: Pop-Up Blocker is not available for Yahoo! Toolbar for Mozilla Firefox. Mozilla Firefox has a built-in pop-up blocker and does not require an additional one.
