My FAVORITE of all DARK themes, at least when using Firefox 29.0.1 (that has abolished the add-on bar) on Windows 8.1 (that has a bug that doesn't allow using very dark themes because of a text readability issue). So this Firefox Personas theme allows me to match it with my dark Windows 8 theme without compromising readability (which would be impossible if it was real BLACK). I also appreciate the fact that the author paid attention to the WINDOWS BORDER COLOR that are all the same (which is not consistent in many other themes). Thank you for the great job.
