I’ve been using an app called Greenshot to take screenshots for years. It has a lot of options but I mainly stick to the “Window” and “Full Screen” capture methods. For the last year the “Window” mode has failed to work with Firefox. It takes the screenshot but the image is all black. Not a huge deal on my small 1920×1080 monitor as I can easily switch to “Full Screen” capture but it sucks on my 3840×1080 screen. Today I had enough and decided to either solve the problem or switch to another app. Thankfully the fix was easy and I’m kicking myself that I didn’t do this sooner!
- Right click the Greenshot icon in the system tray and select Preferences.
- Select the Capture tab.
- Under the Window Capture section tick the Window capture mode option and then change the dropdown to “As displayed”.
- Click OK to save the changes and then give it a go.
