In the new dev channel version you can now have
--incognito = makes all open tabs incognito, but you will lose Most recent page functionality so need a home page setup instead with bookmarks for your regulars.
Also a combination of switches as follows will protect from click-jacking...
-disable-javascript -disable-java -disable-plugins
But will seriously depreciate your browsing experience (try youtube after this
)
--safe-plugins = Chromium also contains an option to run existing plug-ins inside the process sandbox. To do so, run the browser with the --safe-plugins command line option. This setting is experimental and might cause in-stability or unexpected behavior. For example, sandboxed plug-ins might not be able to update themselves to newer versions.
All of the above combined have some negative effects, the most visited page will not work as mentioned so a standard home page needs set up in options, scroogle for instance in https mode, bookmark fav icons will not update, and as mentioned certain auto updates will not happen. Just disable all switches for updates/new bookmarks (or have a separate icon for chrome with no switches).
