I want to restore to a previous version.
i let Firefox migrate my v18.0.2 to v19. I want to restore to v18 because PDF access is too slow on v19. I don't know where to find v18 to install it again. By letting Firefox do migrations, I never actually download and save the versions. I have no idea where Firefox is saving them on my system.
