If you’ve been putting off upgrading or installing Citrix Storefront 3.0, today might be the day that changes your mind. Why? Because today is the day that Google released Chrome 45 which disables NPAPI completely – no more manual-enable-workaround.

September 2015

In September 2015 (Chrome 45) we will remove the override and NPAPI support will be permanently removed from Chrome. Installed extensions that require NPAPI plugins will no longer be able to load those plugins.
