Just make sure to disable search suggestions, or Google gets a peek at your "corner clipboard" all the time.

That isn't true if you set your default engine to DDG or Startpage though! Would be quite the dystopian agreement between Google and Mozilla if so.

I use it for notes too, and being able to update and resubmit my last search easily. And it's probably the core reason why I can't leave Firefox. The tab sync/send is just better too.

I always miss having a separate selection clipboard when I'm on a non-X11 system. Such a useful feature yet missing almost everywhere.
