Awesome Screenshot is one of my favourite applications. It allows you to quickly and easily take screenshots of web pages. The extension is available for Google Chrome, Firefox and Safari.
The great thing about the extension is that you can take screenshots on the fly as you are browsing the web. You can choose to take a screenshot of the whole page, part of the page or just the visible area.
Once you have cropped and edited an image, you can save it to your computer or save it online to Google Drive or temporarily to Awesome Screenshot.
