ScrapeMate Beta is a free Firefox extension designed for web developers and testers to streamline the process of selecting and managing CSS and XPath selectors. This tool provides an intuitive element picker that integrates with SelectorGadget, making it easier to identify the desired elements on a webpage. Additionally, it features a preset JSON editor, which is particularly useful for users working with frameworks like Scrapy. Users can maintain a list of previously used presets, enhancing their workflow and efficiency.

The extension also offers a quick data preview of the currently selected elements, supporting CSS pseudo-elements such as ::text and ::attr(). Users can toggle JavaScript for the active tab, allowing for dynamic testing and scraping. With additional features planned for future updates, ScrapeMate Beta aims to become an indispensable utility for web development and testing.
