ako cesh vec otvarati stranicu u browseru onda ce ti ovo dobro doci, Screengrab ekstenzija za Firefox
The screengrab plugin takes screenshots of webpages in the following 3 ways.
1. Capture the browser window (boring, I can do that with print-screen)
2. Capture the visible portion of the browser window (still boring)
3. Capture the entire document being viewed
The screenshots are saved as PNGs wherever you want them.
