I have just started using Ccleaner 6.02.9938 under Windows 10. Under applications, I have it clean Firefox internet cache, cookies, and history and under system, I have it clean Edge Chromium history, cache, and cookies. After running Ccleaner, I get the messages saying that cleaning was complete and showed the numbers of files deleted in each category. When I restart Firefox however the history is gone but all of my tabs and pages are still there. On the other hand, in Edge, the tabs and pages are all gone but the history is still present and I can reload them that way.
I have been using Ccleaner for years and have never run into this problem using older versions. Does anyone have any idea what might be going on here? I have made sure the browsers were completely closed when running Ccleaner each time.
