Browser 6.0.2 (dev) +++ Download as zip
You can download the latest developer version 6.0.2 of the Browser here.
After unzipping you must move your directory from typo3conf/ext/browser_6.0.2 to typo3conf/ext/browser!
The manual isn't updated.
This is the only cause, why the Browser 6.0.2 isn't available in the TYPO3 Repository.
