Lizard is a Firefox extension designed for web development that facilitates the quick removal of unwanted elements from web pages. With its user-friendly interface, users can initiate a session using a toolbar button or a simple keyboard shortcut (Ctrl+Shift+L). The extension features a help box that provides essential guidance, and an Options page where users can customize their experience. Notably, Lizard remembers alterations made to web elements, applying these changes automatically on future visits to the same page, enhancing user convenience.

In addition to its primary function, Lizard offers a dashboard to manage alteration rules, accessible from both the Options page and the context menu of the toolbar button. The extension requires specific permissions to operate effectively, including access to data for all websites, clipboard input, and notification display. This allows Lizard to modify elements seamlessly and support various operations, making it a valuable tool for developers looking to enhance their web browsing experience.
