1.3G is the grant total of Res and Swap.  You need to read man top
before judging not-entirely-accurate values reported by top.

900M is resident on your main memory. '113+ hours' is not a decent
information to draw conclusion from. Running firefox for 113+ hours
with a single tab on a text-only website is not same as running dozens
of tabs with dozens of multimedia/embedded objects.

You say swap usage was up again but dont give data about it. 472M is
what top would report in the above case but it is an unrealictic
values as it is uncompressed size. output of cat /proc/swaps or free
is what one needs to see.

Also make sure that you put the swapiness value which you say worked
for you in /etc/sysctl.conf.
