Você pode ver que nenhuma opção como restore-session
está listada. Além disso, o documento oficial da Mozilla listou 7 casos quando o Firefox restaurou o sessão, sem mencionar a linha de comando.
Você pode tentar configurar o Firefox para sempre restaurar a sessão anterior em Preferências > Geral > Quando o Firefox iniciar (selecione Show your windows and tabs from last time
) e invoque ./firefox
claramente.
