Continuing to have issues with pinned tabs and, worse, Firefox crashing...like y'day with loss of all pinned tabs on powering up today?! Have posted issue several times with "FredMcD" being unable to help but who escalated the problem...with no response from Mozilla/Firefox! Needlessly spending a great deal of time restoring pinned tabs but sometimes cannot find them all. Does the "800 lbs" Mozilla care?
