I noticed that one had significantly moved in position yesterday - that must mean that some had been opened or closed before it. This morning, the tab itself isn't there any more.
I've tried switching off FF's session saving in favour of TabMix Plus's, but when you come to restart after yet another crash, TMP attempts to reload all the tabs at once rather than - as set up here - only when they are clicked on. The result is another crash.
