I have been using firefox for a long time, but recently the UI on firefox changed from their simple square look to a childish bubbly one. I dont know how or even if its possibe to revert it back. Looking for suggestions and/or opinions on this change. https://i.imgur.com/Z160vhP.png
Looks to bubbly and gives it a childish look to it, while the old one looks more simple and basic.
