Seeing an error "This plug-in is not supported" on Chrome. It shows up on random websites. I haven’t installed any new plug-in, so I wonder what I should do. Please help.

Google Chrome is a free Internet browser developed and released by Google in the end of 2008. Over the past decade, this web browser became one of the most popular browsers and is deemed as the fastest and secure one. Unfortunately, Chrome’s security settings often cross the boundaries by blocking legitimate web domains or preventing people from installing/enabling trusted plug-ins. Many Chrome users reported an error, which says “This plug-in is not supported.”

Chrome does not load random pages and returns the mentioned error message. This may happen due to various reasons, for example, if you have recently installed a doubtful third-party plug-in or upgraded Google Chrome to the latest version.
