Man Snopes is getting really bad. Tons of ads and 3 popups. In Firefox I can hit Control-A to select all text and then right-click and pick Copy to copy all the text. You would have to edit the stuff you don’t want out but it accomplishes the goal.
You can also View> Source and grab the stuff from there.
Even more annoying is that these tricks are pretty much totally ineffective. If someone wants your text or images, they’re gonna get it. Why bother annoying your visitors with it?
Press and hold the right mouse button. The annoying pop-up “you can’t do this” box appears. Keep holding the right mouse button while you hit Enter to clear the box. Now release the right mouse button - and there’s your normal right-click menu. So facile that you wonder why anyone bothers this “protection”.
