How do I fix Google Chrome failed to load plugin?
- 1. Couldn’t load plugin Flash
- 2. Couldn’t load plugin PDF
1. Couldn’t load plugin Flash
As you might have heard, Flash is no longer supported by major browsers. Many video streaming services such as YouTube switched completely to HTML5.
Insisting on using Flash can actually cause errors such as the mentioned one. The right thing to do is to disable the plugin completely.
To do that, simply go to the plugin section in Chrome and disable all instances of Adobe Flash. This will disable Flash completely on all websites.
Furthermore, you can also remove any traces of Flash using a tool from the Microsoft Catalog.
1.1 Update your browser & its components
- Launch Chrome and click on the ellipsis icon in the upper-right corner.
- Then, select Help and click About Google Chrome.
- This will make your browser check for available updates and install them accordingly (if any).
- Additionally, you can also make sure all components are updated.
- To do that, simply type this in your URL address bar:
- Check each element in the list, then restart your browser.
- Then check and make sure all the installed components are up to date.
We took Google Chrome as an example here, but you can obviously adapt the steps to your own browser such as Edge or another.

As such, we recommend you try uninstalling the plugin altogether or simply reset Microsoft Edge to restore it to default values.
