Where is the option to close the current tab when editing the URL in the navigation bar?

This behaviour change happend a while ago and has just now bothered me enough to write up a bug about it. If I have a tab open, navigation bar at the top, I edit the text of the bar and change it to a different URL and hit enter. The current tab I am on is put in the background and a new tab opens for the website I went to. I now have infinite tabs open because they used to close naturally and my back button worked normally and now I have just weird tabs. Also there is no rhyme or reason to the order of my tabs, they used to be chronological, but now I edit a URL and it might take me to the tab from a month ago with it open and then every tab after that is in the middle of a hundred tabs from a month ago. I wish that you would properly complete the changelog for android updates as well as this change in behaviour has taken me from someone who has manageable 10 tabs to a chaotic million that I never close, but won't enable automatic closing of old tabs (which I think was added when this change happened) because I have legitimate tabs open that I want to not be closed. It is just a real suck fest to get to them now since I have so many stupid ones from just editing the URL. TL;DR I want to have android Firefox work like every other browser on the planet when I edit the URL I want to navigate away from the page. When I search I want to navigate away from the page. You took that away and the browser has been worse because of that.
