Clipper - Enhanced Copy & Paste Control

Clipper is a powerful Firefox extension designed to give you back control over your browser’s copy and paste functions. Many websites implement restrictions to prevent copying text or block pasting into forms, but Clipper ensures you can copy, paste, and work freely across the web.

Features:
Unblock Copying: Easily bypass restrictions that prevent copying from websites.
Prevent Copy Detection: Block sites from detecting copy actions, keeping your activity private.
Stop Paste Blocking: Disable websites’ ability to prevent pasting text into fields, allowing seamless data entry.
Prevent Paste Detection: Keep sites from detecting that you've pasted content.

Flexible Control: Configure Clipper’s copy and paste detection blockers on a site-by-site basis. Advanced users can define custom rules using wildcards for precise control, making it simple to choose where the extension should run.
