I've had problems with articles I've saved in my bookmarks concerning information on covid and vaccines disappear. I started using Microsoft as my browser instead and it was worse. As a matter of fact when I transferred my bookmarks from google to Microsoft it didn't or wouldn't even transfer some vaccine and covid related articles I had saved. That's some freaky stuff right there when you consider you are a tiny speck among billions of people yet somehow they managed to scope you out and remove or delete stuff you saved.
