Important information for Firefox users
If you use Firefox with a Firefox account, we strongly recommend that you update CCleaner to version 5.70 before cleaning. This version of CCleaner fixes an issue that can cause extension settings to be lost in Firefox.
The update also includes performance improvements and improved support for Opera GX.
Cleaning
- Fixed a bug where CCleaner could wipe extension settings in Firefox if using a Firefox account
- Added Smart Clean support for Opera GX
- CCleaner now differentiates between Opera and Opera GX processes
- Fixed a rare bug where Health Check would not close all selected browsers
General
- Fixed a performance issue where CCleaner could use more CPU than it needed
- DetectOS syntax correctly supports full Windows build numbers in WinApp2
Errata: Some unfinished improvements to the CCleaner Privacy settings were included in this version before they were fully ready. Having investigated this issue, the data from these settings is being collected correctly and will be applied correctly, so we have left these settings intact so users can start enjoying greater privacy controls right away. You can read more in our FAQs.
