Although there is still a long way to go before it’s ready for Firefox proper, switching to an opt-in, "click-to-play" approach for plugins could help make Firefox faster, more secure, and a bit easier on the laptop battery. A very early version of the "click-to-play" option for plugins is now available in the Firefox nightly channel. Once that’s installed you’ll need to type about:config in your URL bar and then search for and enable the plugins.click_to_play flag. Once that’s done, visit a page with Flash content and it won’t load until you click on it. While HTML5 reduces the need for Flash and other plugins, they’re still a big part of the Web today.
Another popular solution is the click-to-play approach that Mozilla developers are considering. Pluto Scarab — Hash Functions. SMAC - Publications. Anatomy of Facebook. Don't give away your product for free... …unless you plan to keep it free forever.
The Cost of Free Doughnuts, a story on NPR shows what happens when you make something paid that was once free.
