Enable Selection and Copy is a Firefox add-on designed to enhance user interaction with web content by removing restrictions on text selection and copying. This tool is particularly useful for users who encounter websites that disable right-click functionality or prevent text copying. Key features include the ability to bypass copy text protection, enable right-click options, and disable annoying dialog messages that restrict content copying. Users can also benefit from an 'Absolute Mode' which forces the removal of any type of protection on web pages.

This add-on has been modified from its original version to improve functionality, allowing it to work not only on HTTP websites but also on local files. The updated version offers a simpler structure without popups and includes an additional feature for editing web content. Overall, Enable Selection and Copy provides a valuable solution for users looking to navigate online content without limitations.
