The location bar appears empty if a URL contains certain Unicode characters which have a higher line-height than other characters. 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.

Why the heck does "long leftward arrow" need such extreme height in windows fonts? The glyph itself is pretty short.
