Now the button is stuck on my screen after resetting the default settings and uninstalling!

I dont recommend this to anyone as it refuses to uninstall properly. Im going to have to uninstall opera completely and reinstall. 1/5 stars

While the extension has some great ideas and options, it causes everything to lag immensely and also doesnt work well with some sites. I deleted the extension and the settings somehow remain in my browser! I now have to re-install and change them back and take the extension off again, which is a pain.

A website I only ever use in a private tab just showed up in my speed dial.
Its not in my history so Im confused as to how it appeared.

This is completely unacceptable and if it happens again, goodbye opera.
