As I posted in "Vivaldi Speed Dials", CCleaner handles other derivative browsers such as Vivaldi as Google chrome. The user data of other derivative browsers are detected and deleted as Google browser even the lacations of other browser.As I posted in "Vivaldi Speed Dials", CCleaner deletes jumplist (maybe related to speed dial) and then the speed dials are also deleted!
I usually use Avant Browser (http://www.avantbrowser.com/) and it has Chrome engine inside, and the user data are cleared by CCleaner.
I think CCleaner should handle the derivative chrome browsers as separate browser, and do not clear the other derivative browsers!
