What should I do to avoid this? Thanks

    And the code? Note that TeX is breaking it to avoid other undesirable effects so preventing that may make things worse in other ways. TeX tries to choose the lesser evil. Avoiding that evil means preferring a worse one! – cfr Jan 22 '14 at 3:31

Set \interfootnotelinepenalty to 10,000.
