I don't think he's asking how to fix SwitchProxy;
he's asking more of a
general extension design question. And the correct
answer, AFAIK, is
not to commmunicate changes between instances of
your extension via
preference updates, but to prevent multiple
instances of your extension
*in the first place*. Mook's XPCOM (can be done in
JS, C++ not needed)
suggestion is the way to go.
This has been discussed ad naseum at
forums.mozillazine.org. I did a
brief search to try to find some topics about it for
you, but didn't
come up with *precisely* what you're looking for.
Here's a thread which
discusses how to write and register a component in
your extension.
There *are* definitely, however, threads
specifically addressing your
question... do a little more thorough searching, or
simply post there
and ask--someone is bound to have the links.

(proxy configured). The problem is that when
you have
two browser windows open, the status bar is not
in
sync between the two windows. By that I mean,
when
you click the icon in one window, the other
window is
not updated and the instance of the code in that
window does not know that a change happened, so
one
window shows red and one shows green but
obviously
there is only one proxy setting for both windows
so
one window is wrong. Is there a way for the
code in
the first instance to notify the code in the
other
window instances that a change was requested and
completed?
And to clarify my question, I don't just want to
update the icon, but actually somehow notify my
code
in the other instance to update some state and
then
update the icon.
You basically set up a pref observer to monitor a
preference setting
and
when that setting changes you change your icon and
state. Look at how
Flashblock does it. We have a toolbar button that
changes image
depending on
whether Flashblock is enabled or not. Clicking on
the button will
toggle the
enabled/disabled state. This change is propagated
to all instances of
the
toolbar button in each window.
