Today, I ran my existing version of ccleaner. Then, I installed an updated vesion & ran that. A window opened that said there was a RealPlayer Browser Record Plugin available for Firefox, so I checked to install that. A Firefox window opened warning of instability, so I chose to delete it. When installing the update of ccleaner, this is the error message I received: XUL Runner - Error: Platform version '14.0.1' is not compatible with minVersion>=12.0 maxVersion<=12.0.
I did some research and found this information of Firefox: https://addons.mozil...ox/blocked/i106
It seems ccleaner has included something potentially dangerous, along with its update.
Piriform, I sincerely hope you are not making a habit of this. It would ruin your heretofore clean reputation for freeware.
I went into Extensions and deleted that install.
