Interestingly (maybe not), a lot of people seem to be upset about the new address bar. To me, this is the biggest improvement. I don’t have a lot of custom config in Firefox, mainly use it and DuckDuckGo to no be using Google, and find it refreshingly easy to see my search engines and have more information available in a spot that I use all the time rather than having to know where to look or have it hidden in the first place
