Remove colours from toolbars

Thankyou for fixing this addon so it works in Quantam, it's the only add-on I ever, and always, install.

Can you please add an option to colourful tabs so that you can disable changing the colour of the toolbars and background of the back/forward/home buttons, URL etc.

I just want to have it like it used to be where only the tabs are different colours.

Also, if a tab is not open and is in the background it now appears white whereas all tabs used to be different colours. It would be great if that came back as well.
