How to Disable Google Chrome UI Theme Redesign and Return to Classic UI
If you have updated Google Chrome web browser recently you likely noticed there is a new themed visual overhaul called Material Design that comes along for the ride. The new themed Chrome appears to come as the default in Chrome version 69 or later. While some users may be pleased with the new theme look in Chrome and the different user interface, others may prefer Chrome to respect the operating systems default visual appearance instead of using a unique theme.
If you’d like to disable the newly redesigned Chrome browser themed interface, you can do so by toggling a vaguely named setting in the Chrome app.
