As it appears on it's homepage, CentBrowser is the most feature rich Chromium clone out there. It's pretty great with it's customizability and it would be nice if CCleaner added support to clean Cent Browser.
Additionally till that time comes, anyone know how to configure CCleaner to clean Cent Browser for now?
yes, we need that, cent is better than the stock
if it is Chrome based, then this should get you started; https://www.ccleaner.com/docs/ccleaner/advanced-usage/ccleaner-ini-files/how-to-clean-user-data-from-non-standard-mozilla-browsers
instead of MOZILLA, yuou would use CHROME, and of course change the folder location accordingly.
