About

Bug Finder makes exploratory testing easier by providing quick access to common problematic values and edge cases not only through the context menu (right-click) on editable elements, but also through keyboard shortcuts. Keep these useful test inputs handy and insert them effortlessly during your testing sessions.

This extension is a modern continuation of the original Bug Magnet, which is no longer supported by the latest versions of Chrome. It restores and improves the functionality so it works seamlessly in Chrome — and adds powerful capabilities that older extensions never offered, such as fully customizable hotkeys.

Main features:

- Quick access to typical boundary values and tricky test cases for exploratory testing

- Works on input fields and textarea elements

- Fully configurable keyboard shortcuts, with easy reassignment, import, and export of your settings

- Supports multi-frame pages as long as frames belong to the same domain

- Minimal page overhead (<1 KB), no third-party dependencies, completely passive so it won’t interfere with your web app’s functionality
