Starting a day or 2 ago, Firefox's window is badly positioned on the screen - it's bit under a cm to the right and up from where it should be.
Not much more to add. I can drag the window to the correct position - but don't know why it has suddenly started do this. Also, as of today, the Roboform add-on icon has disappeared. Don't know if this is related.
