Recent versions of Firefox have included a new screenshot utility. You might find it useful when you want to capture content within a web page. With Firefox 57 or newer, click the Page Actions button at the right side of the Address Bar then click Take a screenshot.
At this point, you have four options for your screenshot.
- Select a predefined section of the page
- Click-and-drag your mouse to capture a section of the page
- Capture the entire visible part of the web page
- Capture the entire page without scrolling
Now you can save the screenshot to your PC or you can have Mozilla save your screenshot in the cloud for a user-specified duration. The screenshot will be given a unique URL that can be shared with others.
Mozilla has provided more information that you may find helpful.
