I noticed in one of the other threads when Chrome was in its testing phase for becoming portable, some people were having issues with their theme staying saved. Every time they restarted Chrome it was back to the default theme. Mine is doing the same thing and I wondered if anyone found a fix for that yet?
I got the firefox theme for chrome portable, seems to work fine. (I also got the chrome theme for firefox).
Now if you use Iron, you will crash it when you replace default.dll.
