Last month, Google updated Chrome to version 20. As part of the upgrade, the browser’s built-in Flash plug-in was moved from the ancient Netscape plug-in API (NPAPI) to Google’s newer Pepper API (PPAPI). Unfortunately, by default, Chrome doesn’t disable the legacy plug-in and leaves it running side-by-side with the PPAPI one. Fortunately, it’s simple to switch the old one off.
The API used by each plug-in is listed next to the word “Type”. The new Flash will specify “PPAPI (out-of-process)” while the old one will have “NPAPI”. All you have to do is click the “Disable” link next to the NPAPI plug-ins to deactivate them. If you don’t see a PPAPI plug-in, chances are you haven’t updated to the latest Chrome.
Alternatively, if you’ve found Chrome’s Flash capabilities have been letting you down since you updated, you can disable the new PPAPI plug-in.
