So still stuck with no apparent methods to start using Google Chrome for Oracle applications Release 12? Well there is a “possibility”
There is a free extension available with Google Chrome repositories called
Oracle EBS R12&11i Enablement for Chrome 0.1.3
You can download the same for your computer from here (Search in the extensions page with a string like “Oracle R12” as the link location may change later)
Once the extension is installed, close Chrome and restart and try to access the Application instance.
That’s it folks
