Surf the Web anonymously with a simple add-on

Protecting your privacy on the Net is an increasingly difficult task with ISPs becoming more sophisticated in how they track your surfing habits.

However, there are ways to surf anonymously and the Stealther add-on is surely one of the most simple and user friendly out there. Stealther doesn't work via a proxy or encrypt your surfing traces - rather it simply disables your Browsing History (including auto-saved URLs that appear in your Address bar), Cookies, Downloaded Files History, Disk Cache, Saved Form Information, Sending of ReferrerHeader and Recently Closed Tabs list.

The advantage of this is that no trace of your surfing habits is ever stored locally when using Firefox on your hard drive. The disadvantage is that if you need Firefox to store URLs for easy access, it doesn't so you'll have to retype the address in every time you want to access it (unless you have it bookmarked of course). For some reason though, Stealther doesn't seem to work with all web sites, especially those that use encryption of some kind. It can also be frustratingly slow when it comes to loading images meaning your surfing time can be slowed-down considerably depending on the site.

All in all though, Stealther is more effective than using Firefox in private mode. Just be warned that it won't guarantee your privacy on all sites.

Now featuring a toolbar button, statusbar icon, customizable shortcut key, options dialog.Added "Recently Closed Tabs" to functionality.
