Note that current Firefox versions have a build-in feature to take a screenshot as part of the Web Developer Toolbar and you can use this if you only need a screenshot occasionally because you need to use a command line and can't click a button or use the context menu.

  • Web Developer > Developer Toolbar

A quick way to save a screenshot is to press the "s", then the F1 key will bring up a help pop-up where you can click the "screenshot" entry' or use cursor up/down and enter.
You will have to type the options yourself because clicking an entry in the pop-up that appears after the first "-" doesn't work.
The default file name is "Screen Shot yyyy-mm-dd at HH.MM.SS.png" in the Downloads directory.

  • help screenshot
  • screenshot --
  • screenshot --fullpage test_fullpage.png
  • screenshot --clipboard true --delay 5

... thankx so much ... I'm absolutely HOPELESS with the Computer World ... so I will have to look-up: "command line" /" Web Developer Toolbar"/"type the options for yourself"/ and "default file name", before I will be able to test your solution.

... thank you so much .. an enormous help.!!! Denis !!!
