Hello, I use FireFox most of the time but sometimes I also use Safari. Over the past 10 years, on my Mac I have about 30-40 bookmark folders. Some of them should be subfolders. Some folders hold the same category of bookmarks but as I do not scroll through the entire long list of bookmarks all the time, I created another similar folder. What is the best way to manage bookmarks? Am I correct that we cannot have subfolders in FireFox and Safari?
