Hi troy, In my opinion the design is more refreshing & innovative for Firefox. you can always download Firefox ESR for switching back to old version but soon it will be updated. https://www.mozilla.org/en-US/firefox/enterprise/ click this link & click download. Alternatively, if you want to not update you browser you can disable it in you want but it highly not recommended because new version has various security fixes. in the screenshot attached see settings underlined in red & change them to do that. please don't do it unless you know what you are doing.

Hi troytoews69, users have identified a lot of details they don't like, which helps us suggest settings or workarounds to address those issues. Regarding the skin/theme, if you preferred the dark navy blue background at the top, there is an add-on theme to restore that color:

Or if that isn't quite it, you can use the Firefox Color extension to make your own theme:

Let us know whether that helps and what other things are bugging you.
