-<h3>JavaScript Is Powerful</h3>
-
-<p>Back in the early days of the internet, web pages were static, meaning they they contained text and images that displayed on the screen
- but didn't change or interact with the user. Of course, only so much that is interesting can happen with static content.
- Several different technologies were developed to facilitate dynamic web pages. JavaScript was one of these technologies.</p>
-
-<p>JavaScript is a programming language. Many web servers host programs written in JavaScript, which are sent to devices as part of the web page.
- The device runs the JavaScript on its local processor and follows the commands of the program, which can animate images on the website,
- popup a menu, and do many other useful things.</p>
-
-<h3>JavaScript Is Dangerous</h3>
-<p>Of course, the concept of running arbitrary programs from a website is potentially dangerous. So there are limitations placed on JavaScript
- to keep it from doing things like installing viruses on the device. However, it turns out that these limitations are overly broad.
- Below is a screenshot from <a href="http://webkay.robinlinus.com">webkay</a>, which is a website that demonstrates the type of information that
- JavaScript can produce about a device. <a href="http://www.browserleaks.com/">Browser Leaks</a> is another good resource.</p>

-
-<p>For privacy purposes, the ideal would be to browse the internet with JavaScript disabled. However, there are some websites that legitimately require
- JavaScript to accomplish their purposes and others that don't work correctly without JavaScript even though they could be programmed to do so.
- Privacy Browser addresses this by making it easy to toggle JavaScript on and off. Tapping the privacy shield will toggle it between blue
- <img src="images/privacy_browser.png" height="16" width="16"> or yellow <img src="images/warning.png" height="16" width="16"> (both of which indicate
- that JavaScript is disabled) and red <img src="images/javascript_enabled.png" height="16" width="16"> (JavaScript enabled) and and reload the website.
- Looking at the different information <a href="http://webkay.robinlinus.com">webkay</a> can collect with JavaScript enabled and disabled is informative.</p>
-
-<p>Browsing the internet with JavaScript disabled, and only enabling it if needed, goes a long way to protecting user privacy. In addition, JavaScript
- is used to load much of the annoying advertisements and extra cruft that comes along with most modern websites. With it disabled, websites will
- load faster, consume less network traffic, and only contain less annoying advertisements, instead of those that do things like cover up the text of the
- entire web page.</p>
