I also struggled with this. What worked in my case was to (from a content script) create a temporary textarea element that I insert in the document, set the contentEditable attribute on this element to true, and perform the paste: var textarea = document.createElement("textarea"); textarea.contentEditable = true; // insert textarea somewhere in your document textarea.focus(); document.execCommand("paste"); // retrieve the pasted text with textarea.textContent // remove textarea from the document HTH
