Screengrab! is a plug-in for program browser Firefox able to be used to capture fullpage from a website which emerge your monitor screen.
It will capture what you can see in the window, the entire page, just a selection, a particular frame... basically it saves webpages as images - either to a file, or to the clipboard.
It can capture any Java or Flash embedded in a page, but to do this it requires Java to be installed in the browser.
The following little keywords are at the request of those who can't remember the name ScreenGrab! and want searches to work. It takes screen shots, screenshots - that is, shots, of web pages.
