I know how to customize using the typical methods. (i.e. right click the toolbar >Customize... and Firefox>Options>Toolbar layout...) I do not know how to do this manually. As in- locate random file, open with editor, edit line, blah blah blah. So do NOT reply with "have you tried this? or this? or this?" I've tried a dozen different things to no avail... And for the love of cheeznips, do not ask if the toolbar is full, I cannot take anything off of it! Here is the specific issue: I have Firefox 14.0.1 The customize toolbar layout does NOT work. When I try to drag a button from the box to the toolbar... nothing happens. When I try to drag a button from the toolbar to the box, nothing happens.. Using Safe Mode does NOT work either. It doesn't show the buttons I want to Add/Remove.
