Firefox 52 ESR does not support SharedArrayBuffer and is less at risk; the performance.now() mitigations will be included in the regularly scheduled Firefox 52.6 ESR release on January 23, 2018.
ima ovdje neko ko ima ESR? nisam nikad to koristio, ali koliko shvacam on je dosta verzija iza zadnje FF sto znaci da bi mogo snjime koristit sve add-onove koji su mi bitni, bar dok i oni ne dodu do v57 FF?
