Rated 5 out of 5 stars

This is very impressive! And also an amazing example of what can be done, instantly, with a restartless add-on. I, of course, don't know how this all works, but if you can do this much to fundamentally change the entire browser without restarting, well, lets hope installing all add-ons becomes this painless.I can't wait to see what you do with this add-on. It's kind of impractical in it's current form, at least for me, for continuous use, but is a great start and works just as you say, even on Linux and my old computer.

This review is for a previous version of the add-on (2.1-signed.1-signed).
