I have a Firefox addon called Bookmarks Organizer installed and the publisher seems to show a wrong char in Ccleaner version 5.63.7540
Yes Extension Bookmarks Organizer 3.1.0 Sören Hentzschel New Fresh Firefox 74.0a1 C:\Users\gemal\AppData\Roaming\Mozilla\Firefox\Profiles\XXXXXXX\extensions\bookmarksorganizer@agenedia.com.xpi
In Firefox addon interface it's shown as "Sören Hentzschel" which is correct
