Works nicely. But it would just be perfect if it also worked in the new layout, instead of just the old one. In the new layout it just restores the username of deleted accounts, but the comment remains deleted, so I always need to switch to old Reddit to be able to read the comment. It also doesn't restore comments that used Redact. And disabling the auto-expand option doesn't seem to have any effect.

Works very well as promised.

Suggestion: make it also retrieve comments from users who blocked you. The extension can recover the blocker's username but not the comment itself.

It works!
