There's a great way around this with Firefox which I've been using with complete success. The answer is that the block you get when you try to do it using one method, such as right-clicking with your mouse, really amounts to nothing more than unwelcome cyber fiction. When you use the standard keyboard pasting method of the Ctrl + V keys it works perfectly and normally as it should. I've got one domain where I even maxed out the content section capacity that way, and lately I've gotten into adding some affiliate ads.
