Firefox Addon - CSS / JS injector

Hi,

I need an add-on that loads the CSS and JS files when browser starts and inject that code in all websites. I am currently using JQuery and a JS code for that, but it has a delay of 1 to 3 seconds (depends on internet speed) I don't want a delay, I want to load JS and CSS when browser starts so that whenever a user visits website both CSS and JS loads quickly without any delay.

Thanks and best regards
