You say the attack surface is limited to only yourself,
but...
Google "Session Riding", "CSRF" and look at scripts like
this: http://www.spidynamics.com/spilabs/js-port-scan/
to give you an idea of all the things you can potentially
do with an arbitrary script injection vulnerability.
Two important principles to absorb:
1) You don't always know WTH your browser is busy doing
2) It's not always *you* that guiding your browser
