A small collection of Firefox add-ons you can install to improve (a little bit) your privacy – Part 4

What about a “simple” antivirus or a firewall for Firefox? No, a specific antivirus doesn’t exist as add-on for Firefox but an effective firewall could be installed anyway: Bluhell Firewall. Bluhell  is a good firewall with specific features that allow you to better protect your privacy. In fact this add-on is able to firewall all nasty web resources. The big difference between Bluhell and others similar add-ons is that you cannot configure anything. It simply tries to do all the works for you filtering web traffic through seven different predefined rules. At the beginning I was skeptic about the fact I couldn’t personally configure the firewall but when I tested it I was delighted by the results. It is really effective and light so my navigation remains smooth and fast but with a better level of protection for my privacy.

uBlock  is similar to Bluhell Firewall and seems (as for my personal experience) to be a little more “slow” than its concurrent Bluhell Firewall but has the indisputable advantage that you can decide many of its functions. Moreover it is a more classic web filter and you can really decide what to block in a detailed way. uBlock seems to need less hardware consumption  than AdBlocker. About its efficiency I can say that this add-on is not bad and it appears to be really efficient (perhaps more than other more famous…).

Priv8  is a specific sandbox that independently manage one or more Tab. It was built to allow multiple GMail accounts in the same browser when Goole didn’t allow it yet. Now is still a good add-on if we want to visit some websites that we consider not safe. The barrier between the sandboxed tab and the other parts of the browser is not impassable but it is not bad for some common risks. This because the attack will remain finite to that specific Tab preventing an instant reading of cookies and other sensible information you are managing (and, sic!…, temporary saving) in the other Tabs.

Don’t forget that at the end of your navigation it is useful to clean all the temporary files and the Flash LSO (local Shared Objects) stored by your browser.

If you decided to not protect yourself by Flash or if you needed to use it anyway it’s better to wipe common cookies and risky LSO and cookies.

To solve the LSO problem you have a couple of good choices. The first is Eraser , a specific add-on that clean your system everytime you want. It is simple to use and very fast so, for beginners, could improve privacy without headaches.

But if you want a better LSO protection Click&Clean  is what you are looking for. This add-on is really configurable and it allows to automatically run also external Shell Commands and/or applications as Bleach Bit and Computer Janitor. In few words it is effective, fast and user-friendly (highly recommended…).

For more general purposes, AskForSanitize  is another useful tool you may prefer if you want to select what to clean when Firefox is closing down. Usually I prefer to select all the possible options and I am not very interested to “save” anything of my navigation but the fact that a window appears after I close Firefox is a good reminder that my browser is really doing what I want. It could appear silly but the AskForSanitize window reassure me…  

If you want to add a little bit of more security I suggest to install Secure Sanitizer. This add-on has more or less the same features of AskForSanitize but it does the same using (if you choose this particular option) a “US DoD 5220″ three steps wiping. The result is, as obvious, a more accurate cleaning and consequently a more difficult data restoring if you lose possession of your PC and third parties want to know more about your navigation.

To be continued! …with other tips about Firefox add-ons….

Once again about cookies, supercookies and Flash cookies… How to better protect Firefox, your Linux OS and.. you!

In a previous post I already suggested to use HTTPS Everywhere and HTTPS Finder to better protect your privacy on the web. Today I would like to focus your attention on the privacy risks caused by cookies.

Some of them can track your internet activity also when you have logged off from the websites that created them. In few words, some cookies can actively support the creation of a quite punctual profile of your interests and share these information with third parties without you know if your data will be anonymised and correctly stored.

Internet tracking is actual and silent and antivirus software are not the best solution to manage them because every day new types of apparently harmless cookies and supercookies are created and spread into our computers. Cookies usually don’t directly affect your internet browsing but they are a real risk if you want to protect your privacy. A good VPN service (e.g. one that does not link your payment to your “new” assigned VPN IP) could be the best solution but flash cookies, evercookies (a particular type of zombie cookies which are able to geometrically clone themselves outside the original folder where they were stored) could reveal your IP and your habits, just after you disconnect your OS from the VPN shield.

To improve your privacy you can start to combine your VPN with some particular Firefox add-on as Self-Destructing Cookies (for the regular cookies) and BetterPrivacy which has been developed to “search and destroy” Flash cookies.

To improve your privacy, never forget that  you can tune your Firefox Privacy settings also using  Secure Sanitizer which wipe the browser cache in a stronger way than Firefox itself.

Last but not least, don’t forget to “waste” some minutes of your time and use BleachBit after every internet session or every time you shutdown your computer. Better to be slow than sorry!
