HTML5 Privacy Matters: DOM Storage. How to solve it in only 2 steps!

Recently I started an online course that was created using the Google Course Builder.

After I registered the course I was not able to access it because “my browser didn’t allow the web storage” and, for this reason, a message informed me that it would be necessary to use a up-to-date browser as Chrome or Firefox.

The only problem is that I always use Firefox. Obviously a “particular” version of Firefox where I also added a bunch of different add-ons to enhance the privacy protection level of my navigation and, for this reason, the Google course was not available for me.

Normally I would have decided to quit the course because I prefer not to modify my Firefox configuration after I spent so much time searching the best add-ons to preserve a minimum of privacy.  But, in this case, I really wanted to attend the course and so I decided to manually operate on the Firefox configuration to “solve” the problem and allow Google to keep all the information it would have considered as essential.

This is the list of what I did:

– open Firefox and type:

about:config

in the address bar.

– search for:

dom.storage.enabled

and change its configuration from “false” to “true” double-clicking on it.

After this fast change in the Firefox’s configuration menu I was able to attend the Google course but….. I am conscious that my privacy is a little bit less protected because now Google can store up to 5 MB of content on my browser. In fact, before HTML 5 we were used to “cookies” and we were able to “manage” (better: erase) them also if, as the LSO Flash cookies, they were more persistent than usual. Moreover in the old html times, the space available for cookies on your local browser was 4 KB (yes… KB) but now, in the Html 5 era, a single website can easily manage and permanently store till 5 MB on your browser. And this is the reason why I decided to protect my privacy disabling the DOM Storage on Firefox and this is also the reason because I will disable DOM Storage as soon as I complete the Google course…

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

When I read news and reports about modern spyware I am a little bit discouraged about  my privacy. But I also think that something can always be done to improve privacy levels.

This time I don’t want to talk about password strength but I will try to focus your attention on some Firefox add-ons can could positively impact on your privacy.

The first is about Random Agent Spoofer that is able to obfuscate your computer configuration (better: identity) when you connect to a remote server = Internet.

This add-on is really flexible and you will spend just a couple of minutes to decide what  configuration can be useful for you. In particular you can decide how often you desire to change your agent profile and if you prefer to use just desktop agents or to appear as if you were connected through a mobile device. 

Moreover, you can choose if you want to:

  • Send spoofed ‘If-None_Match’ headers (ETags)
  • Send spoofed ‘X-Forwarded-For’ headers                         
  • Send spoofed ‘Via’ headers                                                                     
  • Accept headers match the selected browser profile
  • Spoof accepted documents
  • Spoof accepted encoding
  • Spoof accepted language (US English)

And if you have time you can also play with the many extras as:

  • Use standard font set
  • Disable local dom storage
  • Limit tab history to 2
  • Disable browsing and download history
  • Disable browser cache
  • Disable geolocation
  • Disable link prefetching 
  • Disable dns prefetching
  • Disable webgl

If you prefer a less complex agent spoofer or you are planning to use it seldom, you can use User-Agent Switcher that contains fewer features and needs to be manually configured but it’s intuitive and equally effective.

The second add-on I suggest to install is TrackMeNot that will help to defend your privacy contrasting web search engines profilation with a (huge,-if you want-) number of false queries from your browser. The (huge) number of queries about general topics will obfuscate search engines’ profile about your personal preference. Also in this case this add-on allows you to decide what kind of false queries you want to submit and how often TrackMeNot will “search” the web.

The third recommended add-on is ZenMate, a free VPN service that has obtained positive reviews by the Electronic Frontier Foundation (EFF) also because ZenMate is “based in Berlin and operates under strict German data protection laws”. ZenMate is free, easy to use and let you choose between four different exit node also if using the free base version:

– Germany 

– Romania

– Hong Kong

– USA

Last but not least, keep attention on Flash Files. Do they are so essential for you? You have to keep in mind that sometimes, also if you use a VPN as Zen Zone, you can be betrayed by Flash files. In fact, videos based on Flash can potentially leak your identity also if you try to hide your IP behind a VPN or a proxy.

How to repair Flash on Ubuntu 9.04 Jaunty

This week, in our Linux Page (in Spanish), we have written some easy instructions to repair the flash plugin on Ubuntu 9.04 Jaunty. In fact, after a brand new install on my Acer Aspire Athlon X2 I had big problems in visualizing Flash contents on Firefox 3. I tried to reinstall the plugin different times but the result did not change. Finally, reading a page in ubuntuforums.org I find the right solution for my problem. First of all you have to open Synaptic Package Manager (in System – Administration) and remove all the swfdec packages (in my case swfdec -mozilla and swfdec -gnome). Then, using the Terminal you have to type sudo apt-get install flashplugin-nonfree. Now you restart Firefox and Flash contents will be available again. We believe that this solution is really fast and practical but if you know a better one which could permit us not to install non free code please let us know. AddThis mp3 link
