In firefox preferences there still is an option to switch to old layout with two bars. Sadly it does exactly the same thing as adding search bar manually, that is gives you second redundant search bar and does not turn off search support in the original url bar.

Oh yes, I remember that. I don’t miss it at all, save for the annoying behavior of single bar when a search contains dot (e.g. searching for a dotnet namespace).

While the single bar is my preference I agree that more choice should be given to the end user. Google is trying to hard to shovel the changes that benefit them than addressing user’s needs (obvious example being AMP).
