Now that you mention it...it *is* quite ridiculous, I never thought of it before...to be fair though, it obviously doesn't "bother" me, but it isn't in keeping with the tabbed file-folder design concept. For myself, I am tired of the FF people "fixing" stuff I never use that breaks all the stuff I *do* use. This happens regularly. I have an assortment of older FF versions handy for various OSes, versions I know work for me. Rev. 51 on this extremely current high-powered PC with Win10 is the "latest" version that does what I want bug-free. So I can always go back to it if Quantum/57 fails for me. I use Chrome on machines that "deserve" Chrome (typically smart "appliances"). I jest, it's OK, and if FF worked properly on those machines, that's what I'd use.
