I am on a work computer that is on debian etch and I need Firefox 4. I am not sudo. I have successfully installed Firefox 3.6 with the necessary libraries locally before but since I lost that folder I was really hoping I could switch to Firefox 4.

I have been having a lot more trouble than I thought I would and I'd like to know if there is anywhere on the net where I could get an archive that included Firefox 4 and all the necessary libraries (gtk, libdus and such).
