Fix: “This plug-in is not supported” error in Chrome
“This plug-in is not supported” is an error message that various website media content, such as videos, might display whilst you’re browsing in Google Chrome. That is Chrome’s equivalent of the “Video format or mime type is not supported” Firefox error. Google Chrome, and other browsers, no longer supports NPAPI plug-ins; and media content on a website page that depends on unsupported plug-ins will display the error message in Chrome.
Since 2015, Google has been abandoning plug-in support for its flagship browser in favor of HTML5. As such, the browser no longer supports the Java, Sliverlight and ActiveX plug-ins. Flash is one PPAPI plug-in that Chrome still supports.
Most websites are embracing HTML5, but there are still plenty of websites with multimedia content that need specific plug-ins. Older sites that aren’t HTML5 compatible will probably have videos on them that display the plug-in not supported error message. These are a few fixes that might get the media content working in Chrome without a plug-in not supported error.
Enable Flash in Google Chrome
Flash is the remaining plug-in that Chrome supports, and you can configure Flash with the browser’s settings. So check that the Allow sites to run Flash setting is switched on in Chrome. That will help ensure that the Flash multimedia content works on website pages. You can configure that setting in Chrome 57 as follows.
- First, enter ‘chrome://settings/content’ in Chrome’s URL bar to open Content settings below.
- Now click Flash to open the settings in the snapshot directly below.
- If a Block sites from running Flash option is selected there, switch it to Allow sites to run Flash.
- There is also an Ask first setting there you can select. That enables a click-to-play Allow option that pops up whenever you click to play Flash content on a website page.
- You can also check if there are any pages included on a block list. If there are, click the More actions button beside them and select Remove.
Update Flash in Chrome
Chrome isn’t going to play Flash content if the plug-in is outmoded. You can update Flash by entering ‘chrome://components/’ in the URL bar to open the list of components below. Press the Adobe Flash Player Check for update button to update that plug-in if required.
Add the NoPlugin Extension to Google Chrome
NoPlugin is a Google Chrome, Opera and Firefox extension that enables you to play multimedia content without the required plug-ins. The extension enhances browsers’ compatibility with outdated websites that include plug-in content. NoPlugin converts plug-in code to HTML5 so that the media content plays in your browser. So it can effectively fix videos or animations displaying the plug-in not supported error message. Open this web page and press + Add to Chrome to install NoPlugin.
Open the website page that includes the plug-in media content which isn’t playing. Now the multimedia content might play as expected without any error message. Even if it doesn’t, you can still press an Open content button to save the multimedia file to your desktop or laptop. Then open a media player to play the website’s video or audio. Check out this Windows Report post for further NoPlugin details.
Update the Google Chrome Browser
NoPlugin might not be entirely effective if you’re using an outdated Chrome browser that doesn’t fully support HTML5. Furthermore, updating Chrome can also fix Flash plug-in issues. You can update the browser by clicking the Customize Google Chrome button and Help > About Google Chrome. That opens the tab below which highlights if the browser needs updating or not. Press Relaunch if there are available updates.
Add the IE Tab Extension to Chrome
Internet Explorer is a browser that still supports plug-ins. So you could just open the website pages with that browser. Alternatively, you can turn Chrome into Internet Explorer instead with IE Tab! IE Tab is an extension that emulates the Internet Explorer layout engine in Chrome, which enables the Silverlight, Java and ActiveX plug-ins in Google’s browser. As such, adding this extension to Chrome can fix Java, Silverlight and ActiveX multimedia content on pages.
- Add IE Tab to Chrome from this web page.
- When you’ve added the extension to Chrome, click the IE Tab icon to install the IE Tab helper (which loads the rendering engine).
- Open a website page, and click the IE Tab icon on the toolbar to load it in an IE-based tab.
- You can right-click the IE Tab icon on the toolbar and select Options to open the extension’s settings in the snapshot below.
- Then you can enter the URLs of websites to automatically open in IE Tab in the text box shown below.
- You can also bookmark any page open in IE Tab by pressing the Bookmark this page in IE Tab folder on the toolbar below. Click Customize Google Chrome > Bookmarks > Bookmark Manager > IE Tab to open bookmarked pages.
Both NoPlugin and IE Tab provide the best fixes for Chrome’s plug-in not supported error. They’ll enable you to play multimedia content in Chrome that might otherwise display a plug-in not supported error message.
