  We show how the renormalization constant of the Higgs vacuum expectation
value, fixed by a tadpole condition, is responsible for gauge dependences in
various definitions of parameters in the $R_{\xi}$-gauge. Then we show the
relationship of this renormalization constant to the Fleischer-Jegerlehner (FJ)
scheme, which is used to avoid these gauge dependences. In this way, we also
present a viewpoint on the FJ-scheme complementary to the ones already existing
in the literature. Additionally, we compare and discuss different approaches to
the renormalization of tadpoles by identifying the similarities and relations
between them. The relationship to the Higgs background field renormalization is
also discussed.
