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);
