I'm a bit puzzled by iceweasel. For example, there are some differences in loading of runtime libraries between iceweasel and firefox as follows (obtained using "ldd" after removing numeric location values and sorting): --------------------------------------------------------------- <-- iceweasel/firefox-bin --> local/firefox/firefox-bin 13d12 < libXp.so.6 => /usr/lib/libXp.so.6 32d30 < libjpeg.so.62 => /usr/lib/libjpeg.so.62 39a38,39 > libpangox-1.0.so.0 => /usr/lib/libpangox-1.0.so.0 > libpangoxft-1.0.so.0 => /usr/lib/libpangoxft-1.0.so.0 48c48 < libstdc++.so.6 => /usr/lib/libstdc++.so.6 --- > libstdc++.so.5 => ./libstdc++.so.5 --------------------------------------------------------------- Might these linking choices relate to DFSG concerns? Might they be related to current Mozilla development? As to the visible differences I'm now seeing between firefox and iceweasel, which I find rather puzzling, see the screenshots at http://www.albany.edu/~hammond/gmisc/debiceweasel.xhtml or http://www.albany.edu/~hammond/gmisc/debiceweasel.pdf or, if MathML doesn't work, http://www.albany.edu/~hammond/gmisc/debiceweasel.html -- Bill
