				What Is MassBrowser?
			</div>
			<div class="section-text">
				<p>
					MassBrowser is a state-of-the-art system designed to circumvent Internet censorship. MassBrowser is <a href="https://github.com/SPIN-UMass/MassBrowser" target="_blank">open-source</a> and free-to-use. It has been designed and developed by the <a href="https://people.cs.umass.edu/~amir/Research.html" target="_blank">Secure, Private Internet (SPIN) Research Group</a> at the University of Massachusetts Amherst.
					MassBrowser operates with the help of normal Internet users with open access to the Internet who   volunteer to help censored Internet users.
				</p>
				<p>
					<b>Know your privacy guarantees:</b> Using MassBrowser you will have <b>the same level of privacy as using public VPNs or public HTTPS proxies</b>. Therefore, the volunteer who is  proxying your traffic will know your IP address as well as the websites you are browsing. For HTTPS websites (e.g., any URL starting with "https://"), the volunteer proxy will <b>not</b> be able to see your passwords or other data that you exchange with those websites. This is not true for HTTP websites. Therefore, use MassBrowser as a replacement for public VPNs and HTTPS proxies. If you plan to do something sensitive on the Internet that makes you worried about your anonymity, use a software like Tor (your connections will be much slower on Tor) or tunnel Tor over MassBrowser.
				</p>
				<p>
					<b>Know the security of your local certificate:</b> During installation, MassBrowser asks you to install a <b>local</b> certificate in your Firefox browser.  This local certificate is required for MassBrowser to implement an essential optimization technique called CDNBrowsing (which is described in the geek's section). Note that the certificate is <i>locally created</i> in your browser, is unique for each client, and never leaves your computer. Therefore <b>no one, not even us, will be able to use that local certificate to eavesdrop your traffic</b>.  Make sure you do not share this local certificate  with others. You can simply remove the certificate at any time by going to your Firefox settings.

				MassBrowser's <a href="https://github.com/SPIN-UMass/MassBrowser" target="_blank">code</a> is available on GitHub. We welcome your contribution to the code.
			</div>
			<div class="section-text">
				<p> If you are living in a country with open Internet like US and European countries, we need your help to fight Internet censorship! MassBrowser relies on help from volunteers who share their open Internet access with users in censored countries for a good cause. If you'd like to volunteer, you need to install a software called MassBuddy on your computer. Installing MassBuddy is <strong>absolutely harmless</strong> to your privacy and safety, and you will have <strong>full control</strong> over how censored users will share your Internet (they can only use your computer to get to websites that you approve, like Facebook, Google, etc.). Also, recall that MassBrowser is <a href="https://github.com/SPIN-UMass/MassBrowser" target="_blank">open-source</a>.
				Watch this video (Coming Soon!) on how you can become a Buddy!</p>
				<p>
					Sooo! If you'd like to help censored Internet users, download the MassBuddy software and become a Buddy:
