Google Chrome 21.0.1171.0 Dev not supported! - Better Battlelog Forums #1778

As we have already seen from the title of the topic, this version does not work correctly. I have long been installed and I do not want to change to a stable version. The problem is that the icon can not see the plugin in your browser, no matter how left or right hand side. For greater certainty, I installed it in the portable version 19.0.1084.46. And rabotet without problems. The plugin can be installed but not working. What should I do wait for the new browser or install firefox?
Works well for me, tested with the exact same version.
Maybe test to delete plugin data.
