Very practical add-on. Like it a lot. It makes my browsing life much better organize. Good job. Four stars only as it still seem to be a wee buggy. The backup functionality does not work. In Downloads I have every two hours failed download - files with names stg-backup-yyy-mm-dd@drive4jk.json. And if I go to settings -> backup and try to open backup folder nothing happens. Hopefully soon it will sorted and it will deserve dive starts.
