Dark Reader is an extension that easily inverts the colors on a website. This includes the background, text color, and other items but does not include photographs. It allows for users to add sites to a list that they want to invert, or don’t want to invert (for example, if a site already has a black background). It’s a simple extension with limited options outside of modifying contrast and brightness. The extension remains on when navigating the web. Upon testing, there does not appear to be any formatting issues or missing buttons.
