Is Squarestylist Selector Helper safe?

Low risk

Squarestylist Selector Helper lets HTTPS pages trigger extension clipboard writes through an unchecked message handler.

The extension injects a content script on HTTPS pages and listens for page messages without checking their origin. A page can send a copySelector message with chosen text, causing the extension to write that text to the clipboard through the browser clipboard API or a fallback copy path.
