Simple and Powerful, but not yet on FF5 Rated 5 out of 5 stars
It was great till FF4. Not perfect as missing some useful features...like capturing entire 'page'.
Furthermore, it is not working on FF5 'yet'.
Despite these, I still highly recommend LightShot. I believe the developers will soon bring out upgrade..and this is one damn simple and powerful tool that I use. As long as I can see the capture button, I never failed to capture what I see on the screen.
