I upgraded CCleaner yesterday to the latest version when it was rolled out
I run both the latest version of Chrome and Firefox.. both I use for game scripts on this computer.
I ran CCleaner last evening after upgrading.. cookies was unchecked on both Chrome and Firefox
After rebooting.. my script on Firefox was fine.. but all my settings on the script in Chrome were deleted on 22 profiles.
Prior version did not bother the settings on either browser.
Not sure if this qualifies as a bug, but sure does feel like it
