It might not be common, but sometimes you need an old plug-in, even in this day and age.

While many sites have made the transition to HTML5 for video on the web, you may run into a site that requires older plug-ins such as the QuickTime 7 web plug-in in order to play some videos. While that plug-in has not been enabled by default since OS X 10.9 Mavericks, you can still enable it if you need to.
