Thank you. Excellent.
It works for most websites using the default method. When the default doesn't work (for a minority of websites), you can specify two more methods.

It remembers your chosen method for that domain. You can also choose a method per current tab.

Nice, at frst I thought it wouldn't work with facebook, but then I chose invert and the chat windows are alright again. Thanks for the extension.

Nice One

Is there an extension which can change background colour for New Tab? Every time I open a new blank tab it is so white that my eyes hurt :((( Instead of white i would like black or grey.

Very Cool Add-On!
