In Firefox 3, when you click the bookmark star to choose a Folder, you only get a list of the top 5 used folders. Is there a way to increase this limit to 10 or 15?, since I have lots of bookmark folders and use many frequently.
I looked in about:config and checked all options with the value of "5" and searched for "bookmarks" ect. No luck unfortunately. I don't think you are going to get something like this out of Firefox without some sort of add-on. Searching around there are a few add-ons for bookmarks, but I don't know if they do exactly what you want.
