Since migrating to Mac OS X as my near-full-time platform I have sorely missed SnagIt’s ability to capture full length web pages (scrolling below the fold). For the past few months I’ve been getting by with a cross-platform plugin for FireFox called ScreenGrab. It was slow and could run out of memory on long pages. I was happy to receive an automatic update to the latest ScreenGrab version 0.9.3. It uses the Gecko rendering engine for capturing web pages, making it much faster than the prior Java implementation. You can capture the view port, a selection, or the entire page with a right-click in FireFox.
I use Snapz Pro X for most of my screen capture needs (works like a charm for motion screen capture) but when I need to save a full browser screen as a PNG there is no substitute for ScreenGrab. Yes, I’ve tried Paparazzi but you can’t browse with and that is very inconvenient. This is a show stopper for me because with modern web pages there are, sadly, many states you can’t preserve in a URI. This makes Paparazzi blind to many things I need in my screen captures.
