Release Notes tell you what’s new in Firefox 54.0. As always, we welcome your feedback. You can also file a bug in Bugzilla or see the system requirements of this release.

Today’s release is the first to run Firefox using multiple operating system processes for web page content, making Firefox 54.0 faster and more stable than ever. Learn more about how multiple processes strike a “just right” balance between performance and memory use on the Mozilla Blog. Dive into the details (including performance benchmarks) on Medium.

Firefox 54: more multi-process content processes by https://is.gd/7xLhyI

firefox-multiple-content-processes

Mozilla plans to increase the number of content processes of Firefox’s multi-process architecture to four (from one) with the release of Firefox 54.

Some Firefox installations are still not eligible for Firefox’s multi-process architecture. This includes systems with accessibility tools or settings enabled. Multiple processes won’t be enabled for users with extensions either, regardless of whether those are legacy add-ons, or WebExtensions.

Mozilla ran its memory test again to determine the right number of content processes. An increase in the number of content processes for the browser always goes along with an increase in memory usage.

3 steps to install DNScrypt to improve your privacy – Ubuntu version

Also if you use OpenDNS to improve your standard of privacy, you are not protected by “last mile” dangers but you can boost your security installing DNScrypt on your digital device. DNScrypt “works by encrypting all DNS traffic between the user and OpenDNS, preventing any spying, spoofing or man-in-the-middle attacks”.

DNScrypt “is a protocol that authenticates communications between a DNS client and a DNS resolver” and it “is not a replacement for a VPN, as it only authenticates DNS traffic, and doesn’t prevent “DNS leaks”, or third-party DNS resolvers from logging your activity”.

For this reason you have to be conscious that DNScrpt is just a -very good- improvement of your privacy but not the definitive solution to all your privacy concerns.

DNScrypt is so versatile that you can install it on every kind of device you prefer. In fact it is possible to download DNScrypt for servers, IOS, OSX, Android, Windows and Linux computers (DNScrypt-proxy version). Obviously the installation and setup will vary a little depending the OS you installed on your device.

Here we are talking about DNScrypt installation on Ubuntu.

For this purpose I suggest to use the Terminal that allows you to install DNScrypt i just 3 steps:

sudo add-apt-repository ppa:anton+/dnscrypt
sudo apt-get update
sudo apt-get install dnscrypt-proxy

Last but not least, you need to interface the Internet traffic of your computer through the DNScrypt-proxy. For this reason you have to Edit your Network Configuration and add the address 127.0.0.2 to the “DNS Servers” line as for the below screenshot:

DNSCrypt

Now you can start DNScrypt just typing:

sudo dnscrypt-proxy -R opendns -a 127.0.0.2:53 -u okturtles

Where, in my specific case, okturtles is the name of the remote DNS resolver I decided to use. I chose that specific risolver from the list I found into into my computer after DNScrypt-proxy installation:

/usr/share/dnscrypt-proxy/dnscrypt-resolvers.csv

As usual in similar situations, you may want to spend another couple of minutes to configure your computer to start DNScrypt at the computer boot. Open the Session and Startup manager through the desktop Dash and Add this specific command to the Application Autostart menu:

sudo dnscrypt-proxy -R opendns -a 127.0.0.2:53 -u dnscrypt

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…
