Security Add-ons for Firefox

Firefox is my browser of choice. The number one reason for this is the add-ons that can be installed for increased functionality. Some of these add-ons are useful for making Firefox more secure. These are some of the add-ons that I recommend:

Adblock Plus
While I have some reservations about blocking ads, because they are so useful to businesses for bringing in new customers, they have also been a growing avenue of attack. Cyber-criminals have found ways of hacking ads that get posted on otherwise ‘safe’ websites. The website of The New York Times is a great example. Adblock Plus uses constantly updated lists to block ads from loading. This should theoretically stop some maliciously hacked ads from loading as well.

What about malicious elements that aren’t ads? Well you can use NoScript to block all active elements from running in your browser. This will certainly add security to your browser, but it will make a lot of websites look much different. For convenience, you can set-up rules on a per-site basis.

Web of Trust
Web of Trust or “WOT” places color-coded dots next to results on major search engines, and one in your toolbar for your current page. Furthermore, it blocks poorly rated websites from loading with a big warning screen. These ratings are community based, and if you have this add-on you can rate and comment on sites yourself. The comments can be very useful for evaluating others’ experience with a specific website/company.

Long URL Please
This simple add-on will automatically lengthen any shortened URLs from services such as This way you can tell at a glance where they go.

PassIFox integrates the KeePass password management tool with Firefox. KeePass is a great program for generating and storing complex passwords. KeePass deserves its own blog post so look for one in the near future.

Better Privacy
This may be more privacy related, but the borders between privacy and security overlap. Better Privacy deletes Local Share Objects. Excerpt from the creators:

Why are LSO’s harmful?
  • they are never expiring – staying on your computer for an unlimited time.
  • by default they offer a storage of 100 KB (compare: Usual cookies 4 KB).
  • browsers are not aware of those cookies, LSO’s usually cannot be removed by browsers.
  • via Flash they can access and store highly specific personal and technical information (system, user name, .).
  • ability to send the stored information to the appropriate server, without user’s permission.
  • flash applications do not need to be visible to the user
  • there is no easy way to tell which flash-cookie sites are tracking you.
  • shared folders allow cross-browser tracking, all browsers use the same LSO folder
  • the company doesn’t provide a user-friendly way to manage LSO’s, in fact it’s incredible cumbersome.
  • many domains and tracking companies make extensive use of flash-cookies.
  • flash-cookies are used to re-create data of deleted traditional cookies.

Qualys BrowserCheck
This one is new to me, but very handy. It checks to make sure your browser and its plug-ins are up-to-date. This can be particularly useful for techs.

In conclusion Firefox add-ons not only add functionality, and personalized touches to the browser, they can also help increase your security. If you do not have Firefox try it out now, and find out how amazingly customizable it can be.
