Browser doesn't use all the memory that's virtually allocated to it.
A bit more realistic figure you get with:
pid=<PID>;
for type in Private_Dirty Private_Clean Shared_Dirty; do
awk "/$type/ {sum += \$2}
END { printf(\"$type:\t%6d kB\n\", sum) }
" < /proc/$pid/smaps;
done
"Dirty" is memory that has been written into i.e. it needs to be swapped
out if there's not enough memory (instead being just discarded and being
paged back from root file system if/when needed).
