For me: Flash.  Either "standard" flash, or nspluginwrapper-flash --
both require 32-bit libs somewhere.  (nspluginwrapper so that its 32-bit
binary and the flash library can use them; standard flash so that both
the FF binary and the flash library can use them.)

There is a 64-bit flash plugin now, of course.  This may change the way
I think eventually.  :-)

(Also, for some people, the Java plugin may be a reason, although I am
not one of those people.  But there may be a 64-bit Java plugin as well
now; I'm not sure.)

One other reason is the availability of 64-bit XPIs for FF extensions --
last time I looked, there were no prebuilt 64-bit XPIs, only 32-bit.  So
to run any kind of extension on a 64-bit FF (such as web developer or
Venkman, which I use *all* the time), you have to compile it yourself.

Finally, mplayer can't use (32-bit) w32codecs, or the realplayer codecs,
if it's been compiled for 64-bit.  Obviously this means that all your
real open-source codecs also need to be compiled for 32-bit (boo!), but
there's no good way around this that I know of.

(In short: anywhere anyone would be using anything closed-source or
easier to obtain as a binary may introduce a need for multilib.)
