When I run health check it clears Firefox browser history and removes sign in usernames and passwords. How do I stop it from doing that? I have CCleaner Professional v5.78.8558 (64bit)
You can't stop Health Check doing that, it uses it's own cleaning rules that you can't change.
Instead you have to use Custom Clean which lets you have more choice over what is cleaned or not.
For what you want in Firefox you would untick 'Internet History' and 'Session' in the Firefox section, when unticked Custom Clean will leave them alone.
(It's 'Session' that keeps your current logins).
Note that those settings have no effect on Health Check which will still do it's own thing and still clear the history and logins if you use it.
To set Custom Clean as the default you see whenever you open CCleaner go to Options>Settings>CCleaner home screen
Thank you nukecad for the reply. I have Firefox in-ticked in custom clean but thought that health check would honor that.
No, Health Check always does it's own thing.
If you could customise Health Check's privacy/space cleaning then it would be the same as Custom Clean.
