Insert style sheets and JavaScript into the current page or the current tab temporarily. The difference between this add-on and Stylus and other similar add-ons is that Stylus automatically inserts style sheets into pages that match the URL pattern, but in this add-on, the user manually inserts a style sheet on any page by clicking a button. The purpose of this add-on is, for example, to insert a style sheet temporarily to make it easy to read when encountered a page that is difficult to read, such as using an image as the background or a color with low contrast.
