I have a number of folders on my bookmarks bar in firefox. I'd like to be able to change the icons for a few them to match the category they represent. Is this possible? If so, how?
My suspicion is that it's not built in to firefox itself, because changing the icon is what distinguishes a normal bookmark from a folder (it would break the UI metaphor they're using). But I'm not opposed to using an extension for this, if one exists.
