Noteworthy Add-ons for Firefox Users
HTTPS  Everywhere is an add-on developed by The Tor Project and Electronic Frontier Foundation that forces certain websites to use the secure HTTPS protocol instead of the standard HTTP protocol. At the moment, the number of sites it supports is limited to the more popular services on the web; Google, Wikipedia, Twitter and Facebook to name a few. However, custom websites may be added so users can access other websites that use the HTTPS protocol. By using this add-on, or by accessing HTTPS websites where possible, you increase your level of anonymity. For those that are interested, here is a list of websites that are fully supported;

• Faceboook
• GMX
• Google
• Ixquick
• Live (Hotmail)
• Meebo
• Microsoft
• Mozilla
• NY Times
• PayPal
• Twitter
• Washington Post
• Wikipedia
• WordPress

WOT is an add-on that promotes 'safe browsing' and advises users which sites are considered 'safe' and which are 'not so safe' based on a ratings system. It uses traffic light colours to indicate the level of safety for a site; green is considered safe and trustworthy whereas red means not so safe and generally untrustworthy. With the program being so easy to use, any member of the family can use it, including children and the elderly. It's not just available for Firefox either, it's available for most of the major browsers including Google Chrome, Safari, Internet Explorer and Opera. Once you've installed the program, you'll become part of the WOT Internet community, and have the chance to rate websites. WOT helps you make informed choices about the websites you visit, and by avoiding untrustworthy and potentially 'dangerous' websites, you increase your level of anonymity.
NoScript is a popular add-on that blocks JavaScript, Java and Adobe Flash elements. All of these are capable of revealing your true IP address and/or compromising your system. With NoScript, you can manually select which elements you wish to run. If you're the type of person that regularly watches videos on YouTube, then it's most likely that YouTube is obtaining your true IP address every time you watch a video, regardless of the fact you're using a proxy or VPN. I would suggest that you download the video via a service such as KeepVid. NB:  Some websites need Javascript, Java or Flash to work properly. Verify whether you trust the website and be selective.
CSLite is an add-on that controls how your system deals with cookies. Cookies are small files which store information about you on your visit to a website. They are stored on your local computer. Obviously, we don't want lots of websites to store cookies on our computer, so this add-on allows you to manually allow cookies for websites that you trust. NB:  Some websites need cookies to work properly. Verify whether you trust the website and be selective.
AdBlock Plus is another popular add-on that blocks adverts on webpages. The reason why it's so popular is because it does exactly what it says on tin; it blocks ads making your web experience that little bit better.

Scroogle is a simple anonymous search engine. It's basically a stripped down version of Google's official search engine without all your information being exposed. No frills, just anonymity.

10 Minute Mail is a disposable e-mail service. This service is especially useful for signups and activations where you do not want to disclose your real e-mail address. This acts as a good spam prevention method. A random e-mail is generated and is updated automatically when e-mails arrive. As the name suggests, the mailbox only lasts for time minutes until it self destructs. However, if you need to use the mailbox for a little bit longer, you can request another 10 minutes quite easily and repeat as many times as required. Highly anonymous as your mail is destroyed after 10 minutes. You can not send e-mails using this service.
Yopmail is a disposable e-mail service. It is a little more sophisticated than 10  Minute  Mail and allows you to define your own e-mail address @yopmail.com or generate a random one. The accounts last for 8 days and then it expires. Again, useful for signups and activations where you do not want to disclose your real e-mail address. You can only send e-mails to other Yopmail users using this service.
