The URL is still in the location bar, and can be highlighted, but is pushed down, below the visible area. This also occurs in pop-up windows, essentially hiding the true page the user is on. This could be used in phishing schemes. Reproducible: Always Steps to Reproduce: 1. Enter URL with special characters in URL, eg. %E2%9F%B5 2. Hit enter Actual Results: Location bar does not show URL. Expected Results: Location bar should always show URL. Firefox should either not allow such characters in the location bar, or display them differently.
