after updating to FF Quantum, my lastpass extension works fine in FF but not in private mode. In a private window it doesn't show the UI for the extension when the icon is clicked. works fine in normal window. I've tried installing previous versions of the plugin, but any version above 4.2 gives same error. The extension works fine in FF which is not quantum version When i click on the options in extensions -> lastpass, it doesnt display options too. where as other addons have no problem displaying the options.
