UPDATE: W00t! There is a fix for Snapper to work with FireFox 2.X Go here for an updated xpi file. I installed it new on my home PC. At work I’ll uninstall the old add-on and then instaff the fix.
*UPDATE* – This add-on is not compatible with FireFox 2.x
I wish I could claim first sighting of this but I found it on Darlene Fichter’s Blog on the Side. You can get Snapper from the Firefox Add-Ons site. Snapper allows you to define an area of the screen and save it as a .png file (portable network graphic). When snapper is installed, a red fish appears in the lower right corner of the browser window. Click on it and the mouth opens. Right click on your starting point and make a box around the part of the screen you want to capture. When you release the mouse button, a window will open for you to tell it where to save the graphic. You can also change the name of the file from the default. It doesn’t have all the bells and whistles of screen capture programs such as SnagIt but for a quick and as-is snapshot it is great.
A .png graphic can be rendered any graphics program you are likely to be using.
