Open a new tab
Type (or copy and paste) chrome://plugins/
Find the plugin called Adobe Flash Player and click disable. The plugin should be greyed-out. You should also make note of the version of the current plugin to know when the new one has been updated.
And that is it! Simple, right?
Once the new patched version becomes available, simply make sure you are running the latest version of Chrome and enable the plugin.
Note: When you disable Flash, you will not be able to view any content that runs on it, so simply enable the plugin if you want to view that content.
I hope this was useful. Let me know if you have any questions.
Have a nice weekend!
