Ugh, Flash content, right? It slows everything down, and buries content within inaccessible Flash movies, and forces you to install and keep updating the plugin, even if you don’t need it.
Honestly, I hope Flash goes the way of the dodo, and HTML5 takes over. If I had my druthers, I’d disable Flash on my Mac
Until then, however, there are some sites where you actually need to enable Flash to see the content. So, instead of completely dumping Flash in a fit of pique, you can enable it in Safari only for specific sites.
