So I had a bunch of green time at work and installed a buttload of Firefox extensions. I like them and also want to install them at home, but without writing down the names of each of them and searching for them on mozilla.org

Is there any way to just export all of my themes/extensions from work and import them at home, preferably without uninstalling or overwriting any of the extensions I already have installed?

I tried looking for .jar files, no dice
