Indeed, running under valgrind showed only insignificant memory leaks (11kB) when loading the munin page. After further playing I also found, that FF indeed releases the pixmaps in the xserver when tabs are "replacing" the closed tabs with many graphics, i.e.: 3 open tabs, close two, open two new empty, then FF seems to release most of the X resources (pixmaps) of the closed tabs.
