Save Screenshot από Manuel Reimer

This is a very simple screenshot taking addon. You can use it if your primarily work with screenshots in external image editing applications or you use the (unmodified) screenshot to archive pages.

Top features:

• Full-page screenshots without scrolling. No duplicated headers all over the image!
• Image formats: PNG, JPEG or lossless copy to clipboard
• Capture regions: Full page, current viewport or selected region
• Context menu in website and popup for the button freely configurable in the Add-on's settings. If you enable only one of the options for "Image format" and "Screenshot region" you can create a screenshot with just one click
• Flexible shortcut support which allows to define up to 9 shortcuts for specific screenshot settings
• Custom filename format possible
• Metadata, like screenshot date/time, page title and page URL, are saved into the image as image comment (optional, can be disabled if you don't like it)

Please note:

For some pages like addons.mozilla.org and a few other Mozilla pages, it is impossible to take screenshots as addons are not allowed to run on these pages. If this happens, the addon will display a notification to you to tell you that creating a screenshot is not possible on this page.
