5-12-24: they have a convoluted and time consuming method of selecting portions of a page that does not work many times, so you waste a lot of time trying to get it to work properly. Can't handle large pages, freezes system, sometimes requiring hard reboot. No way to easily report bugs. down to one star, would give 0 if possible. FFox must be hard up for programmers to recommend crap extensions like awesome. Want to waste your time trying to get this script kiddie pos addon to work, then install it. Can't handle browser zoom settings, can't select proper portion of page. Waste a lot of time trying to get this POS addon to work. Obviously the "developers" don't know shyt.
Mozilla should hold a contest because there ARE NO good scrren savers extensions for it.
11-7-23: Clips the image so download is incomplete. SLOWWWWW. Freezes computer on long pages with no progress bar.
In windows 8.1 when capturing a large page, it runs roughshod on your memory and your computer will freeze up often requiring a reboot. Does not work on portable browsers that are not integrated into your OS. Slow to load, run and save an image.
