Since the latest Firefox update, apart from it changing the Theme, it's expanded my bookmarks menu so that it now runs off the page and I have to scroll down to read the ones at the bottom of the list. This is annoying. (Why do they have to keep fiddling? A colleague of mine used to say 'improvement means deterioration'. Very true).
Anyway, how can I edit the way my bookmarks are displayed so that the lines are closer together, and I don't mean spacers (although I've inadvertently put one of those in that I now don't seem to be able to get rid of, Grrr!). I can't believe there isn't a way to alter all sorts, but I can't find the key.
