I hate it too, and yes the current layout is way better. I'll try it, but I might try other browsers too. I hate that most times a ui for a phone is updated it reduces the number of functions presented, becoming simpler and cartoony. Sometimes a feature or setting you used previously takes longer to get to, sometimes it's gone. (Not firefox for the features being gone entirely part, that I've noticed)

They are also experimenting new tab design. I hope they will also add tab groups.

Not a huge fan of adding a "new tab" button to the search bar. Its already super short when your phone is vertical and even worse with the protection thingy icon and reader mode.
