My system: Win 8.1 Prof - updates are up to date
When I use the "cleaner" function while firefox is off, the program stops with the message "Ccleaner does not function" and I have to finish the program.
When firefox is on, I am asked to finish the browser. In case of refusal the cleaning works fine, however without cleaning firefox.
Conclusion: Ccleaner has problems with firefox.
Please finde attached the error report.
What can I do?
