User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0 Build ID: 20171210100145 Steps to reproduce: "This connection is not secure, Logins here can be compromised" can appear on top of input boxes, making it impossible to see what you're typing (e.g. vBulletin 4). This is extremely annoying since it pops up right on top of the whole input field, and it's also really annoying to get rid of (you need to click somewhere else and as soon as keyboard focus is back it reappears) and easy to accidentally click in an attempt to get around it, which is really frustrating. Actual results: "This connection is not secure, Logins here can be compromised" completely covers up input box Expected results: "This connection is not secure, Logins here can be compromised" never ever appears such that it covers up an input box, but always below/above
