thanks

This is the point! Unless your hobby is tracking browser updates, you'll never know exactly if and when CCleaner is compatible with a specific browser.... As I guess the guys at Piriform are checking any compatibility issue with existing browser, it would be quite easy for them to disable or at least warn a user on potential issues

If this CCleaner strategy, you will never be safe. Authors may update products in a way CCleaner may be fooled and spoil data. The only safe way is to stick to a version check: over an unverified version, disable!

As I wrote, for future versions I would stick for a version check, disabling risky operations on unsupported versions.

CC 4.04.4197 just destroyed my Chrome (Version 32.0.1700.107 m) prefs. Fortunately I had previously synchronized settings with my Google account. Maybe you should choose to verify what version is supporting, disabling Chrome settings when Chrome version is greater than xxx, forcing users to upgrade CC to the latest version
