Google Chrome offers several different parameters you can pass in when you launch the application. Use them, you can disable components of Google Chrome.
- -disable-extensions disables extension
- -disable-images inhibit Google Chrome from loading images
- -disable-java disables Java
- -disable-plugins disables plugin
- -disable-sync inhibits bookmark sync feature
- -incognito opens browser in incognito mode
Those parameters need to be passed in the command line. (or if you are using Windows, you can also add those to your shortcut, too.)
For instance, the following would disable both plugins and extensions. (thus no Flash, etc.)
chrome -disable-plugins -disable-extensions
Also there is -proxy-server, which you can also make Google Chrome access through proxy server. (Useful if you are creating SSH tunnel, for example.)
One caution is that in order to use this, you will have to make sure that all instances of Google Chrome are closed, or this will not work.
