Fix is probably lost somewhere in a buroucracy scheme "Assign_Dumb-Not_A_Bug-Result_Of_Our_Great_Feature-Won't_Fix". Sigh. Mozillish classic is never old. 11 years is nothing. BTW, CTR addon is a bugfest. Hide Caption Titlebar Plus is THE WAY to fix GUI changes and to add new features you will like. Another signs of unhealthy fox' fauna are: slow or absent user's common knowledge update and also ignoring by mozilla ff devs ideas only because they are based by previously changed GUI.
