It can be really annoying when you are using a button in the AOL Toolbar one day and then the next day it’s missing. This may happen because another plugin in Firefox is conflicting with the AOL Toolbar. Removing the last installed plugin will resolve this issue.

To uninstall the most recent plugin:
1. Open Firefox.
2. Click the Tools menu, then click Add-ons.
3. Click the Plugins tab.
4. Select the most recent plugin installed, then click Disable.
5. Click the X to close the Add-ons window.
6. Exit Firefox.

The next time you open Firefox, the plugin will be uninstalled.
