Http剪贴板 is a lightweight script tool designed to address issues with the navigator API on HTTP websites. This free Chrome add-on allows users and developers to enable copy functionality on non-HTTPS domains, which is typically restricted. Once activated, users will see a notification in the upper right corner of the webpage confirming that the content has been successfully copied to their clipboard.

The tool is straightforward to use and integrates seamlessly into the browsing experience. It specifically targets the limitations imposed by browsers on HTTP sites, ensuring that developers can enhance their web applications without requiring a switch to HTTPS. This add-on is particularly useful for those working with legacy systems or during the transition to secure protocols.
