Looks like a problem with the package from http://ftp.de.debian.org. Either it did not download properly or the package is broken. Try deleting the package /var/cache/apt/archives/libpng12-dev_1.2.8rel-1_i386.deb then redo the apt-get install command. If this does not work, try 'apt-get -t unstable install mozilla-firefox' (or apt-get -t stable install mozilla-firefox) to get a different package from unstable or stable instead of testing or change your sources list from 'http://ftp.de.debian.org' to 'http://ftp.debian.org' (edit /etc/apt/sources.list). Apt-get update again, of course.

I have tried everything with apt-get that are mentioned in these forums but I still get the same error message

Processing was halted because there were too many errors.
E: Sub-process /usr/bin/dpkg returned an error code (1)

frozen-bubble is removed but it is the frozen-bubble-data that breaks everything.

I've tried to install the stable, unstable, changed sources and tried the --purge command

I can't install anything because of this, please help

Try this: http://www.knoppix.net/forum/viewtopic.php?p=49772 for frozen-bubble.
For libgtk2.0-common, just wait a day for it to get hopefully fixed.
