I am testing web applications. I therefor always need a browser that does not have any cookies, saved logins, etc. Put shortly: a fresh instance.

As we just work with Chromium, I wonder how to start such an fresh instance.

I don't want to set up my regular Chromium installation to not save cookies and such. I want an extra instance.

You can create a new window in a temporary profile or use incognito mode. – Salem Jun 5 '13 at 9:37
@Salem Well, that would work. – mcbetz Jun 5 '13 at 9:43

There are two ways to solve that problem:

  1. Open a new window in Incognito mode (Ctrl+Shift+N) (thanks to @Salem) for temporary usage
  2. Create a new profile with chromium-browser --user-data-dir=/new/directory. In this new profile, you can switch off all cookies, plugins, etc. and restart it with the same command whenever you need it.

BTW those options can also be accessed with a right click on the Chromium launcher icon (with Unity). – Salem Jun 5 '13 at 11:32
