Just in case you don't know: If you hit the "Print Screen" button on your keyboard (usually in the upper right), you'll take a snapshot of whatever is on your monitor at that moment.
Then open a new Bitmap Image document on your desktop (right click). Then right click on the Bitmap, choose Edit. From there you can paste your "Print Screen" snapshot.
This is a handy way to save an internet page that might later on mysteriously disappear.
Thanks!
THANK YOU! All these years and I didn't know that.
Thought I needed a 'screen grab app' or Firefox add-on like that.
