Dark Reader is a plug-in for Firefox, thanks to which we can run any website with a dark graphic motif. This tool can be used at any time, but Dark Reader is mainly designed for users who work on a computer at night. The program not only allows you to turn on the dark graphic theme, but also allows you to adjust a number of settings, including brightness, contrast, sepia and grayscale.

There is also an option to change the way text is displayed.
