The newest feature for Firefox 14 - called "click to play", will basically work as a built-in Flashblock plugin - if you're not familiar with what it is; I'll explain: if you choose so, plugins like Flash or Java will no longer load by default - you'll have to manually launch the plugin.
Doesn't sount that useful? Well, if you thought that, I have to tell you that you're wrong.
Plugins have certain vulnerabilities - and can easily be exploited, which results in malware being installed without the user even knowing what's going on. Some websites can "plant" files on your computer via these plugins - all you need to do is open their page. That's why having to run plugins manually (instead of having them run automatically as soon as you visit a page) is a much more secure way to go.
I, for one, am very glad to see that the guys at Mozilla actually care about the safety of their users. A large portion of people browsing the internet isn't educated enough on the potential dangers to their privacy, and aren't even aware of what a plugin like Flashblocker does.. Making something like this a default option for all users will definitely increase your security on the internet.
Good job Mozilla!
