There's an update rolling out for Chrome right now that adds a new menu to the top-right of the app that lets you manage users. It's ugly and a bit obnoxious if you don't switch profiles often. Here's how to disable it.
All you need to do to disable it is head into your flags menu.
- Type in chrome://flags/ into the URL bar
- Search the page for "Enable new profile management system"
- Change the drop-down menu to "Disabled"
- Restart Chrome
That's it. You'll lose the user management menu and return to a simpler version of Chrome.
