On a certain social network website, when I click on the profile name of a person or subject, a small pop-up should occur showing me the profile of that person. However, now, it pops up at the entire screen instead of the smaller pop-up as has been for 5 or 6 years. If I double click on the top bar, it automatically reduces to the correct size. I've already done the "Mozilla Safe Mode" way and reset the settings, but it is still happening. How can I make this go back to the original way of just opening in a small popup?
