Im having issues for the last few week now with ccleaner, when i run ccleaner, clear everything, then open firefox, firefox then has my history, and gives me a this is embarrassing issue page. or will load up my previous web page before i clicked run ccleaner to clear it.
image attached after running ccleaner, firefox still has my history
happening on two computers now, one last last weekend, clean installation, and now second pc is having same issue
Excluding a file just means that CCleaner will leave it alone and not clean/delete it.
Firefox is making some big changes at the moment, it's going to take the developers at Piriform a while to work out just what has changed - and as soon as they do FF will change again in the next few months.
