Please INSTANTLY fix FF 57 so that Sessions Manager and also Tab Mix Plus (the most valuable add-ons of all !) will work again.
It is really a shame for the FF developers to have simply "discarded" this extremely useful tool - a tremendous mistake that (for the first time ever !) makes me question FF and my use of it !
