Problems opening pages with the warning "To protect your security, (site) will not allow Firefox to display the page if another site has embedded it."
This warning appears on so many pages since up the Firefox update that it's making it difficult to actually use Firefox. And your suggestion "To see this page, you need to open it in a new window", doesn't work. Clicking option + the link doesn't offer a chance to open a new tab or new window. And the block is still there when I copy and paste the desired link. Two of the biggest issues are on highly reputable sites (a bank and a telecom). I suggest you fix this "upgrade" because other browsers don't have this problem.
