I have a problem with Firefox Beta 53. It doesn't happen in Firefox 51. Sometimes notification "Logins entered here could be compromised" appears above context menu when I right-click in password field, depending on how fast right-click happens. Sorry, I don't want to tell you exact sites I visit, but it this scenario should work 1. Open http://example.com in a new tab and execute the following line in web console: document.body.innerHTML=`<form method="post" action="/"><input name="L"><input name="P" type="password" size="12">`; document.querySelector("[name='P']").focus(); 2. Quickly right-click the second input field on the page. ("Quickly" means that 'mousedown' should be immediately followed by 'mouseup') Result: The notification appears above context menu, covering some of the menu items. I don't remember their order. Expected: All menu items should be visible. Or the notification shouldn't appear at all. As I've said in bug 1344390, I would appreciate any advice on removing the notification forever, because it seems annoying. In case I get the advice, I won't see the notification at all, so I won't ever encounter this bug, and it can be closed then.

I could not reproduce the cover problem, but see the notification flashes almost every time when right clicked on insecure fields.

Because I said problem on the above, keep this bug open.

This is a known issue being fixed in bug 1337772
