For the arrows, it is a bug in Firefox, which does not support 
stretching of operators in mtable cells (BTW for this kind of diagram or 
more complicated ones you can use MathML embedded in SVG, which is 
supported by Firefox but maybe not by other renderers).

For the integral sign, it is an instance of the "stretchy bug" in 
Firefox, and more specifically of largeop that are not drawn larger (in 
MathML 3, integrals are "largeop" but not "stretchy", to follow what TeX 
does). Last week, I've made available some unofficial binaries for 
people who want to test:

https://build.mozilla.org/tryserver-builds/fred.wang@free.fr-try-08c872a8d318/

In the testpage complex1-full.xhtml, sum and product symbols should 
definitely look better. The rendering of the integral sign is slightly 
improved, but it seems that in general Firefox should draw integral 
symbols a bit larger again...
