Alternative Fix: Troubleshooting your problem

It’s most likely because you have some bad settings or bad installation of other toolbars on your internet browsers. In this case, I would suggest you to uninstall all kind of toolbars from your browsers and re-install one by one to troubleshoot the problem.

If nothing else works, we recommend you to use Google Chrome. Most of the features offered in Google toolbar are built into Google Chrome browser.

Alternative Fix 3: Uninstall and reinstall your current browser

Before installing, make sure to backup your bookmarks and anything else you can’t afford to lose, and then uninstall Firefox from the Add or Remove programs. When backup and uninstalling are done, proceed to install the latest version of Mozilla Firefox. Lastly, try to install Google Toolbar again.

As for Internet Explorer, in most cases, IE will be automatically updated via Windows Update. Check and see if your Windows Update is right intact and run as usual. If it isn’t, make sure to turn it on. Sometimes Internet Explorer update will be grouped as optional update, you will have to manually select it to install it from the Windows Update window. When you have your IE updated to the latest version, try to install Google Toolbar again.
