@sgunhouse This is meant to provide a browser for machines meant for being servers...so I don't want to have anything installed locally. The browser should reside on the network share but might be used by multiple users concurrently. I haven't tested much, but installed the portable version to a mapped share (X: -> \file-server\share, Opera installed to S:\Opera ) and added the switch to the launcher (X:\Opera\launcher.exe --user-data-dir=S:\Opera\datadirs%COMPUTERNAME%). That doesn't account for the possibility of concurrent users from the same machine. I chose portable only because I assumed the app would be more self contained and more suited from running from a share (or USB).
My goal is to have a simple and secure browser that can be run from a share from concurrent users.
