Bookmarklet to Copy All Links on Page

This version only copies links that point to external domains:

javascript:(function(){
  const currentDomain = window.location.hostname;
  const links = Array.from(document.querySelectorAll('a[href]'))
    .map(a => a.href)
    .filter(href => {
      try {
        const url = new URL(href);
        return url.hostname !== currentDomain;
      } catch { return false; }
    })
    .filter((href, index, self) => self.indexOf(href) === index);
  
  const text = links.join('\n');
  navigator.clipboard.writeText(text).then(() => {
    alert(`Copied ${links.length} external links!`);
  });
})();

This version includes the link text or title with each URL:

javascript:(function(){
  const links = Array.from(document.querySelectorAll('a[href]'))
    .map(a => ({
      url: a.href,
      text: a.textContent.trim() || a.title || 'No text'
    }))
    .filter(link => link.url.startsWith('http'))
    .map(link => `${link.text} - ${link.url}`);
  
  const text = links.join('\n');
  navigator.clipboard.writeText(text).then(() => {
    alert(`Copied ${links.length} links with titles!`);
  });
})();
