Posting a screenshot on the forum
From MozillaZine Knowledge Base
Posting a screenshot when describing a problem is sometimes helpful. To do this, set up the programs the way you want them to appear in the screenshot, then:
Creating a screenshot
Windows
- Press the Print Screen button on the keyboard, normally to the right of F12. Nothing will appear to happen.
- Open an image editing program such as Photoshop, MS Paint, Paint.NET, or The Gimp.
- Press Ctrl+V to paste the screenshot into the program.
- Edit the picture to highlight whatever you wish to point out. (draw a red arrow or something)
- Save the screenshot as a PNG.
- Close the image editing program.
To take a screenshot of a single window, focus the window, then hold Alt while pressing the Print Screen key. If you need even finer control use a screen capture program such as MWSnap or PicPick that let you specify any rectangular area.
Mac
- Press Cmd+Shift+4.
- Drag a rectangle around the item you want as a screenshot. A file called something like "Picture 1.png" will appear on your desktop.
To take a screenshot of a single window, press Spacebar after pressing Cmd+Shift+4, then click the window.
Linux
- Press the Print Screen key. A window will appear offering to save the screenshot as a PNG. You can hold down ALT to only capture the active window.
