Click to play for plugins (Flash, Java) in Firefox

In Google Chrome, there is an option to enable “Click to Play” for plugins, such as Flash, Java, or Silverlight. This makes the browser safer (especially after all the Java security vulnerability in the last time) and a little bit fast. Today, I found out that this option exists in Firefox too – although its a little bit hidden.

To enable “Click to Play” in Firefox…

  1. go to about:config and click on “I’ll be careful, I promise!”
  2. search for plugins.click_to_play and set it to true (by double-clicking the entry)

After that, when you get to a page that contains Flash (videos), Java, or any other plugin, you’ll get a “Click to Play” message for the plugin.

Plotting graphs with R

This post is about how to display (draw) a mathematical function with R.

Side note: There’s a very nice and interactive tutorial for R available over at codeschool.com. It’s free and takes about 3 – 4 hours to complete.
