For goodness sake, *please* allow us to control/turn off this DOUBLE LINE SPACING in the BOOKMARKS SIDEBAR!
I've spent hours online looking for a fix, but as you've also disabled the userChrome.css method of solving this problem, I'm stuck with bookmarks which now need a scroll bar. There is no gain to the double spacing at all, which looks terrible and reduces function by wasting my time. Why did you do this AGAIN, despite all the user feedback?!
