One of the best screenshot addons Rated 5 out of 5 stars
I've tried more than a few screenshot capture addons, and Pearl Crescent PSB is one of the best. Unlike the others, this gives the option to set shortcut keys to capture the page. It also allows one to remove or keep context menu items, (very important if you like simple menus)!
The length of pages this addon can handle is impressive. Whereas other addons gave me errors on long pages, Pearl Crescent Page Saver saved images almost 33,000 (yes, 33 THOUSAND) pixels in length! Wonderful addition to Firefox. :)
