Is xerobank XB Browser truely USB Portable? Can I run it off a USB stick without installing anything to the host computer? I've been running Firefox since v1.5 from a batch file with the -p profile switch. With it I save my profile to the usb stick off of \Firefox_2.0_Profile. No surfing history or anything else ever gets saved to the host computers drives. Does XB Browser place anything on the host computer? If so how can I get it to save it to a USB stick folder? Ever will there be a truely portable version released in the PAF format (like those at http://portableapps.com) that installs directly to a portable USB drive and doesn't make any changes to the host computer? Are there any command line options I could use with XB Browser? If so please post them all as a seperate post. Also I had a devil of a time trying to download the program with either Firefox from the batch or Firefoxportable v2, and V3. Please see if it can be posted to a couple of FTP mirrors. I was doing all this at my college library. If I hadn't stumbled across a copy of "Opera-Tor" that didn't get blocked I could have never downloaded it. It's sure a whole lot faster than "Opera-Tor".
