Google Chrome is one of the top famous search engine and ChromePlus is built on top of Chromium, open source project behind Google Chrome.
ChromePlus has all features that Google Chrome has, but it adds extra functionality such as Mouse gestures, Super drag, double click to close page, IE Tab and download tools supported in context menu.
Once you download and launch ChromePlus, it will automatically import settings from Firefox. Below is the screenshot of the ChromePlus options page:
If you are a Google Chrome user and want to have features like Mouse gestures and IE Tab that only available in firefox, then you should give ChromePlus a try. hopefully these features will be included in next Chrome release.
