The problem is that in possibly different situations (clicking the address bar,
typing into the address bar, both), the address bar expands larger than it
normally is.

I dont mean that a drop down list of websites is presented. That does happen,
but I am fine with seeing the websites. I am not fine with the larger size
address bar. I dont want it. I want the address bar to be the normal size
ALWAYS. It seems it was possible previously to disable this via
"browser.urlbar.openViewOnFocus" or maybe some other similar options.

Again, I dont want some option to disable this some of the time, I want it
always disabled. Currently this seems to only be possible with CSS hacks. Surely
this is not the case? Surely such a distracting change wasnt made without regard
for users who might hate it?
