Are you looking for a screenshot utility for Firefox that will tie in with your Diigo account? Then you may want to have a look at the Awesome Screenshot – Capture and Annotate extension.
By default the extension will add a new toolbar button and for our example we left it in place. When you are ready to take a screenshot you can choose to capture only the visible part or the entire page as needed.
Once you have taken the screenshot you can start modifying it by adding text, arrows, lines, and shapes to annotate and highlight areas of the image.
When you are finished you can save the image online temporarily, on Diigo.com permanently, and/or to your hard-drive.
If you prefer to work without the toolbar button you can access the extension through the Context Menu.
Here are the options for the extension. You can choose the image output format and set up custom keyboard shortcuts if desired.
Note: Works with Firefox 4.0b7 – 4.0.*, does not require a browser restart!
