Mozilla Firefox released version 75 of the popular browser the other day. Firefox is my browser of choice on my personal machines and I quite like it a lot. However, with the new release they added an "enhancement" to the address bar, which I rather call bloat. What it does is make the box larger in all directions when it is in focus. I suppose that is to help the user see better where the cursor is and what the browser is focused on at the moment. I get it, but I don't like it.
Thankfully, Firefox is open-source and we can tweak the browser to our needs and liking. There are a few things in the about:config section that we need to adjust to put the address bar back to the way it was before the update to version 75.
First, open a new window or tab and in the (bloated) address bar go to the configuration section and tell it you're sure of the "dangers."
Then in the seach bar on this screen, search for these settings and flip them around.
browser.urlbar.openViewOnFocus = false
browser.urlbar.update1 = false
browser.urlbar.update1.interventions = false
browser.urlbar.update1.searchTips = false
Once you get these changed, close are restart the browser and you should have the good 'ol address bar back without the bloat.
Update: If you've updated to Firefox 77 since this post was released, the above settings no longer work. See this new post on how to fix the bloat.
