Full page screenshots in Firefox, Safari and Microsoft Edge
Firefox and Edge can capture a full page with a built-in tool, Safari on Mac needs its developer tools, and Chrome hides the command in DevTools. Here is how each one works.
Take a Firefox screenshot with Ctrl + Shift + S or right-click > Take Screenshot: save the full page, the visible part or a region, then download or copy it.
Take a Microsoft Edge screenshot with Ctrl + Shift + S: capture the full page or a selected area, draw on it, then copy or save. Plus when to use Windows tools.
Take a Safari full page screenshot: on iPhone tap Full Page after a screenshot, on a Mac use Web Inspector's Capture Screenshot or save the page as PDF.
