firefox missing dependency icu-data-full

With firefox it is not possible to enter a money amount like 30,00 in some german banking application (sparkasse-emsland.de), while with chromium all works fine.

chromium has dependency icu-data-full whereas firefox has icu-libs only, that depends on icu-data-en.

So icu-data-en is proved insufficient in any non english localisation.

Adding dependency icu-data-full to firefox will solve such problems.
