To enable cookies on Firefox for Android '''click the three dots in the top right area of your Firefox browser''', it's just below the new tab plus (+) sign. Then navigate to '''SETTINGS''' and then '''PRIVACY'''. Once on the '''PRIVACY''' screen you will see the '''COOKIES''' button, click it and your choices will be '''ENABLED''', '''DISABLED''' or '''ENABLED (EXCLUDING 3RD PARTY)'''. I hope this answers your question.
