Works even with Portable Firefox Versions Noté 5 sur 5 étoiles

It works even with the portable version I'm using (like this: "...\FirefoxPortable.exe -preloader"). Improved start up speed is quite noticeable, perhaps twice as fast (or perhaps even only a third of the previous start-up time) with the about 50 add-ons I'm using. For me this add-on is definitely a keeper. Thanks!
