Localstore.rdf and firefox.js

Hi,

I'm using FirefoxPortable and I have some trouble. In fact, I want to modify the localstore.rdf to have a special window size but it doesn't take in account.

Moreover, if I have a firefox (2.0 or 3.0) install on the PC and I launch my FirefoxPortable, FirefoxPortable ask me to update my extensions (I have no extensions in FirefoxPortable) and I would like to not have this question because it depends of all PCs and My firefoxPortable have to be the same.

this is what I have in my App/Firefox/defaults/pref/firefox.js

pref("app.update.auto", false);
pref("app.update.enabled", false);
pref("extensions.update.enabled", false);
pref("extensions.getAddons.showPane", false);
pref("extensions.update.autoUpdateEnabled", false);
pref("extensions.update.notifyUser", false);
pref("plugin.default_plugin_disabled", false);
pref("ui.key.generalAccessKey", 0);
pref("ui.key.chromeAccess", 0);
pref("ui.key.contentAccess", 0);
pref("ui.key.menuAccessKey", 0);

and this is what I have in my Data/profile/localstore.rdf
