i get Japannese or china charactors in my tool bar have to close then restart to remove

Unfortunately, you probably need to disable McAfee Site Advisor on the Add-ons page. Either: * Ctrl+Shift+a * "3-bar" menu button (or Tools menu) > Add-ons In the left column, click Extensions. Then you can find it on the right side. Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the page and click one of the links as the last step. Success?
