Help! Google Toolbar & 404 Status

I'm not sure what you're after here? You have an optional browser plugin that you voluntarily installed that is interfering with your normal browsing experience. It seems you should be asking the maker of that plugin to fix it (since it is happening on sites that aren't built on CI as well, such as Bing), or uninstall it so your browser works normally again. If the plugin doesn't handle standard 404 headers correctly I'm not sure what can (or should) really be done about that by anyone except the plugin manufacturer.
