I lost my profile folder and could recover just the jsonlz4 bookmark files but there is no way to open it each file I try using the normal procedure in the restore option I get an error saying "unable process the backup file", I'm about to give up but just want to try one last time to know if there is a possibility to get them back since they are from 5 years now and all the information I have there is important. Thanks in advance.
