I just stumbled upon a really cool thing that firefox did after a long time... (of course firefox 3.5 as well). I always wondered and wished there was a way where i can get my fav extensions bundled together.
Especially when there is a system crash or you lose your browser settings (read extensions) by any means. Look what we finally have - a collection of extensions bundeled together for your taste and purpose to help you work.
You can choose from array of collections already available, create your own collection & download an Add on collecter for your personal bundle.
