I still stand by my previous statements. Mozilla certainly improved on overall performance with Quantum, but to say Firefox was unusuable is actually not even an exaggeration - I stand corrected on this - but plain wrong. AFAIK, Chrome did introduce the multi-process approach but that touched tabs only peripherally. Tab management itself has not improved.
