Screenshots (Topvisor) is a Chrome add-on developed by Topvisor that provides a convenient way to take high-definition Retina screenshots from any screen, but only in Firefox. This program offers a range of features, including quick page markup and the ability to draw directly on the webpage.

With Screenshots (Topvisor), users can easily draw lines, arrows, text, circles, rectangles, and numbered callouts on the webpage. It also includes a blur tool for obscuring confidential information. The magnet mode allows for precise drawing with alignment to webpage elements such as text, buttons, forms, and links.

While this add-on offers great functionality, it is important to note that it is only compatible with Firefox. Users of other browsers will not be able to take advantage of the high-definition Retina screenshots and quick page markup features provided by Screenshots (Topvisor).
