Google has scrubbed plans to fully integrate its Chrome web browser with Microsoft's new Windows 7 operating system.

The news follows an announcement by the Mozilla Foundation that Firefox 3.6, the next version of the open source browser, would integrate with Windows 7 features such as taskbar thumbnail previews and Jump Lists.

However, according to reports in The Register, Google's internal issue tracking system indicates that work on the features has been pushed back to version 5 of the browser. Chrome is currently on the 3.0 release, while version 4 is currently in development.

Despite the scaled back ambitions, work seems to be progressing on Google's Chrome OS. An early developer build of the operating system has been leaked onto Google's website. Stay tuned for more details.
