Browser View accepts command line arguments for incognito private browsing mode. For command line arguments, other than incognito private browsing mode, use the Browser View Plus (PlayLink) add-on.
For IE, Opera, Chrome and most other Chromium browsers, users may open these browsers, for incognito or private browsing, by entering "private" as the command line argument. Browser View automatically changes "private" to the proper browser-specific command form at run-time.
For example, to always open the Chrome browser, from Firefox or SeaMonkey, in incognito private browsing mode-- add "private" to your browser location, in Browser View Menu Settings, as follows:
"... \chrome.exe private" (or "... \chrome.exe --incognito").
