New Tab button and List Tab Button Rated 4 out of 5 stars

I tried the add-on but then uninstalled it. I have the new tab button disabled in user-chrome and the list tab button disabled in preferences, since disabling this addon, they are BOTH back on the tab bar and there is no way I can find to get rid of them. Any suggestions?

This review is for a previous version of the add-on (0.8.1-signed.1-signed).
