I would expect a "Referer" value to be empty in both cases:

  - directly navigating to a URL after doing a copy-paste
  - opening a link from an email

It would be awesome to see these kind of tools taken to the next level. So far we are "just" doing Zettelkasten in computers.

What I mean by the next level is something like:

- when I pick up a new e-book, show me the chapters that have new ideas that I'm not familiar with yet, so I can skip the things I already know

- let me see how my ideas/opinions on a given topic were evolving through time, which encounters have influenced them

- let me publish a slice of personal knowledge base for others to explore, let me see what my friends published (better social media?)

This is the relevant bug report: https://bugzilla.mozilla.org/show_bug.cgi?id=734643

Apparently, it has something to do with the UI rendering the selected items, and not with the database.

Hot damn, opened 8 years ago? That report describes the behavior I experience to a T, it's definitely the same bug.

Is the this 'Library' window a dead component? Besides this nearly decade-old bug, it still doesn't get themed like the rest of firefox either; dark mode doesn't effect it.

If you think that's bad, wait til you see the bug date for X11 exploit on Linux systems.
