I accidentally installed a toolbar in Google Chrome and I want to remove one that I don't use anymore, here's how I do it. I've been experiencing performance issues with Chrome, it may well be a toolbar that is causing problems so I follow this procedure to check I've got any installed. Note that the process is exactly the same on Windows as it is on Google Chrome for Mac.
1. Click the Customize and Control symbol in the top-right corner of Chrome
2. Go to Extensions along the left-hand column and you'll see the toolbars that are installed. Click on the dustbin symbols on the right next to each extension to remove them.
3. Confirm the removal and you're done.
