I worked at a company that makes forensics software and was interested in
seeing if it could pick up Incognito browser history. I opened Firefox
and set it to "not remember any history," then cleared the history and
browsed to a few web sites. I also tried this with a private browsing
tab, and with Chrome in an Incognito tab. Then I took an image of the
hard drive and loaded it into our forensics software. The web sites I
visited did not show up. I also checked for other traces (e.g. images
from the browser cache) and did not find anything.
I also used a
hard drive hex viewer and did a string search for a couple of the web
sites I went to, and they weren't on there. So the browser developers
appear to have done their job in keeping browser history off of your
hard drive.
