It works on the Comodo Firefox offshoot IceDragon too - I would guess that the Comodo Chrome offshoot Comodo Dragon would work too, but I normally used it in private browsing mode.
I like Ice Dragon Firefox and use it as my main browser now, including Disconnect add-on. Other Firefox add-ons I would recommend are Karma Blocker (pretty simple to whitelist sites you want to allow, and other sites get rated based on the number of adverts etc.), Google Privacy (works for other major providers such as Yahoo and Bing) and Ad-blocker for Gmail.
Also, if you haven't heard of it and want an alternative to Google, try the DuckDuckGo search engine at "duckduckgo.com".
