If I have multiple footnote citations of the same reference on the same page I get multiple footnote entries with exactly the same content.
\begin{filecontents*}{\jobname.bib}
@article{test,
title = {Synthesis of Enantiopure Alcohols},
volume = {71},
number = {17},
journal = {J. Org. Chem.},
author = {Test T.},
month = aug,
year = {2006},
pages = {6333--6445}
}
\end{filecontents*}
\documentclass{report}
\usepackage[backend=biber]{biblatex}
\addbibresource{\jobname.bib}
\begin{document}
First\footfullcite{test}, second\footfullcite{test} and third time.\footfullcite{test}
\end{document}

I find this to look weird and wondered if something like this was possible:
1,2,3 Test T. “Synthesis of Enantiopure Alcohols”. In: J. Org. Chem. 71.17 (Aug. 2006), pp. 6333–6445.
If the output in my minimal example is completely normal I am happy to leave it that way - I would just like to hear some opinions on this.
UPDATE: I have done some further research on this and I reckoned it would be the simplest if a footnote citation occurred twice on a page it would get the same footnote.
First\footfullcite{test}, second\footfullcite{test} and third time.\footfullcite{test}
would give
First [1], second [1] and third.[1]
Conclusion: My first proposal is very hard to achieve and unnecessary complicated. The solution using "ibid" solves this problem in a different but effective way. If one did not want to use "ibid", Audreys post solves the problem very nicely, too.

biblatex, so can 't comment on that, but the more usual "extra" footnote content would be "Ibid.", i believe. – barbara beeton Jul 19 '13 at 18:18\footfullcite(or even\fullcite), you are tellingbiblatexto give the full reference regardless of any other considerations. There are other ways around this, but using\footfullcitein each case is making a solution harder, not easier. – jon Jul 19 '13 at 21:29
