If you are a serious browser/user of the web, you know Mozilla Firefoxrnis tops when it comes to remaining secure. But even Firefox is not perfect.rnThere are always ways to improve the already outstanding security in the openrnsource browser with add-ons. The Firefox add-on library is massive and includesrnnearly any additional feature you could want. Included in the library is anrnever-growing number of security add-ons. For those that do not want to wadernthrough the tide of installable features, I have brought together five of myrnfavorite security add-ons for Firefox. With these five added features, yournshould find that Firefox will meet your highest security standards (withinrnreason of course).

Each of these add-ons are free and can be found (andrninstalled) from Firefox’s add-ons manager.

1. NoScript Security Suite

NoScriptrnSecurity Suite is one of the best ways to prevent JavaScript, Java, Flash,rnSilverlight, and other executable content from running within non-trustedrndomains. With this add-on you can dictate the domains which are allowed to runrnexecutable content. This add-on goes a long way to prevent cross-site scriptingrnattacks, cross-zone DNS rebinding, router hacking, and Clickjacking. Domainsrncan be blocked permanently or on a temporary basis (Figure A).

Once installed, yournwill also find a number of ads get caught up in the blocking u2013 making your browsingrnfaster and more secure. NoScript has plenty of options available, ranging fromrnthe simple to complex (Figure B).

2. LastPass Password Manager

LastPassrnPassword Manager is for anyone who needs to be able to keep the only kindrnof truly secure passwords u2013 those you cannot remember. For that type ofrnpassword, you need a password manager. But why bother installing yet anotherrntool to have to open from your Dash, Start Menu, or Tiles? Instead, addrnLastPass Password Manager and gain access to that ever-burgeoning list ofrnpasswords. You do have to create an account with LastPass. During the setup ofrnLastPass, you set up your account (make sure you use a strong password here u2013 FigurernC) and disable Firefox’s insecure password manager.

During the setup ofrnLastPass, you can even set up a profile which will be used when filling inrnforms (Figure D) u2013 which is much more secure than having the browserrnretain your form information.

3. HTTPS Everywhere

HTTPS Everywherernis a means to force your browser to use HTTPS with all sites that supportrnsecure HTTP. Some users don’t realize the difference between HTTP and HTTPS;rnincluding this extension on your end-users browser will ensure you do not havernto concern yourself with educating them on the difference or how to point theirrnbrowsers to the secure version of a site. You will notice the included linkrndoes not direct to the Firefox Extension page, but to the www.eff.org page. This was due to a Firefoxrnpolicy. Hopefully the extension will find its way back to the Extension pagernsoon. Upon reboot (after installation), you will be prompted to opt into thernSSL Observatory (Figure E).

4. AdBlock Plus

AdBlockrnPlus is one of the first add-ons you should include with Firefox. If yournfind advertising slows down your browsing, it’s possible that reduction inrnspeed is caused by advertising. Or, if you’re trying to find that tool torninstall, but get confused by the Download buttons created by advertisements, it’srntime to take control. To curtail this behavior, install AdBlock Plus. With thisrnadd-on you can blacklist and whitelist specific advertisers. This, of course,rnis a tricky proposition, as many of the sites you visit are able to offer yournfree content thanks to the ads on the site. So take that into considerationrnwhen you begin blacklisting sites. It is also possible to block known malwarerndomains (Figure G).

Bottom line

Each of these offers a unique addition tornthe open source browser, extending the capabilities and security to a morernacceptable level.
