Too much space in menu dropdowns Rated 3 out of 5 stars

Unfortuantely, with the release of Firefox 3.6.13, the "Mostly Crystal" theme stopped working, and I was force to go to this theme; the closest one to it. I would have used this theme long ago, but for one thing — there is so much wasted space in the menu dropdowns. The leading (space between vertical lines) is ridiculously huge in this theme, making a previously small dropdown flow off the bottom of the page. Is there any way to reduce that spacing in Crystal Qute back to normal?
