I have opened a webpage that has an article of very much interest to me. When I use Ctrl+P or right click, it says, "The page forbids you to use any additional commands."
So now how do I print such a page or save it as a PDF, at the very least?
Some websites prevent you from using keyboard shortcuts because they are worried that you will steal content such as trying to save an image by right-clicking on it. Try using the browser's "Print" option in the top menu, instead of Ctrl+P or the right-click menu.
Click the wrench icon (upper right) and then choose "Print...".
Click Firefox (upper left), go to "Print..." , and then choose "Print...".
Click the gear (upper right), go to "Print", and choose "Print...".
In Chrome, you can click the "hot dogs" icon in the right upper corner and choose Print....
In Firefox, you can click the Firefox icon in the left upper corner and choose Print....
Take a screenshot (see the accepted answer), crop in image editor to remove browser controls, do whatever you want with the image.
