on xfce4-term the linespacing looks about 1.5 compared to Droid sans Mono.

Costs to many lines on screen, nice font though.

I have the same issue. A sad thing, the font looks good but the line spacing is way too much for my taste.

Download Fira Mono OT from https://bugzilla.mozilla.org/show_bug.cgi?id=897009#c64, and you'll get 30% more lines.
