It certainly can.
Any compromise of one account (security bug in mozilla) will only gain
the attacker access to the oen account. The attacker will have to then
elevate privilages to the superuser to do anything with the other user's
files (which may contain important/sensative information).
Of course, you should always keep up on all security advisories, and
when using a system like this even the lcoal ones may present a serious
threat (normally they're priority 2 on a single user system as they need
to be fixed, but cannot be touched unless a remote exploit is also
avaialbale).
Basically, any steps you take to separate privilages are useful.

and e-mailing as user2.
There is a default firewall, and neither user has the permission to read,
write, or execute any file that belongs to the other user.
My question: will this little extra step improve my security over the
regular way
of doing web browsing under the same user?
