I like it, but... Rated 4 out of 5 stars

This is simple and works well. But Google Chrome has an option - one of its 'selling points' - to surf using a so-called incognito window or tab. This keeps no cookies, passwords, history entries. Windows shortcuts to launching Chrome can easily be made to open the incognito mode by appending
-incognito
(it must have a space preceding the word) to contents of the Target field in the shortcut's Properties. I imagine that many like me would want a Firefox button that switches over to a stripped-down (more private) browser. So what about an option on this add-on, or just a second similar add-on, that defaults to that incognito mode of Chrome?

This review is for a previous version of the add-on (0.1.5). 

Thanks for the suggestion

Thank you for this suggestion. I have put it on the feature request list, but I cannot promise a special date for this. In the meantime, you might want to consider using Launchy (https://addons.mozilla.org/firefox/addon/81) to launch Chrome in incognito mode.
