thank you for your review. All extension settings are stored in permanent storage that survives browser closing, even PC restart. Do you have some 3rd party cleaning app, that would be deleting "unnecessary" files. Or maybe some company policy is set?

Hi,
thank you for your review. If you wish your search results to be without "rating score" badge, then open extension UI by clicking its icon in address bar, navigate yourself to the settings in right top corner and uncheck "Mark my serch results" - next time you search something badges will be gone.
