Blocked plug-ins

Google Chrome blocks plug-ins that are outdated or those that are not widely used because they can occasionally be a security risk. Plug-ins help browsers process special types of web content, like Flash or Windows Media files. Some plug-ins, such as Flash, are used by many websites on the Internet. Other plug-ins are only used by a small number of sites.

Examples of plug-ins that Chrome blocks:

  • Java
  • RealPlayer
  • QuickTime
  • Shockwave
  • Windows Media Player
  • Adobe Reader prior to Adobe Reader X
  • Unity
  • Google Update
  • VLC

Run blocked plug-ins

You can run some plug-ins even if they are blocked by Chrome. Chrome will ask you for permission to run a plug-in and you should only run plug-ins on sites that you trust.

To let the plug-in run on the site, follow these steps:

  • To run the plug-in just this once, click Run this time. The plug-in will run, but if you visit the site later, you'll be asked for permission to run the plug-in again.
  • To always allow the current site to run the plug-in, click Always run on this site. Subsequent visits to the site will run the plug-in without asking again.
  • To always allow this type of plug-in to run, go to chrome://plugins, find the plug-in and check the box next to Always allowed.

Learn more about managing plug-ins

If you don't want Google Chrome to ask your permission before running lesser-used plug-ins, use the command line flag --always-authorize-plugins. Instructions on how to add a command line flag can be found on our Chromium site
