Google Chrome blocks plug-ins that are outdated or those that are not widely used because they can occasionally be a security risk.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:
- Windows Media Player
- Adobe Reader prior to Adobe Reader X
- Google Update
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.
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
