Setting up Firefox

/ browsers, firefox, add-ons, how-to

I have previously said you probably want to, or at least should want to, move away from Google Chrome as your web browser. I also listed a couple of alternatives, but reading back I noticed I wasn't more specific in how you can, and probably should, set those alterntives up. Let's start with Firefox.

After some deliberation I have now decided on going with Firefox as my main web browser. I had some good time with Vivaldi, but unfortunately Vivaldi isn't available on my mobile devices. It is still my second browser on my desktops though, and I do have it fully configured etc.

On my mobile devices I had some good experiences of Brave browser. Then I learnt that Brave browser had some worrying funding schemas going to extreme right-wing groups, and also that the former (sacked) Mozilla CEO, who was funding campaigns out of his own pocket to stop LGBT-people from marrying etc, now was working in Brave, I figured I should revisit my options, as there are some things I do not wish to support.

Set up Firefox

Firefox has been around for a while, and its latest generation of browsers are top-notch. They have also built in privacy concious controls for pretty much everything, and if you know what settings to tweak and what add-ons to...umm...add, it can be made very secure, privacy concious and still usable. Furthermore, it works fine on all platforms, such as desktops and mobile devices. It also can sync your bookmarks and other settings between your devices. In short, you can have all the benefits of Google Chrome, without selling your soul, and your data, to Google.

It should be noted that you should aim to keep your add-ons to as few as possible. The more add-ons you add, the more likely you are to become an unsuspecting victim of bad code somewhere, so add-ons should be carefully considered before installing them. Having said that, I will be suggesting a couple of add-ons that you should install, which can help you increase your privacy.

If you have downloaded Firefox and you wish to use the multi-device sync functionality, you are probably going to wish to create a sync account, but this is entirely optional. If you have multiple devices and you do not wish to create an account, you can instead set up Firefox for each of your devices. I like having a sync account though, so I'm going to assume you do too.

General preferences

Preferences - Content Blocking
Preferences - Content Blocking

Next you should open up your "Preferences" and go to the "Privacy & Security" settings. Start with scrolling down to "Firefox Data Collection and Use" and uncheck all the boxes there.

Whilst you are in Privacy & Security, find the section called "Content Blocking". There are three options there: Standard, Strict and Custom. I have mine set to "Custom", with the following block settings:

  • Trackers (In all windows)
  • Cookies (Third-party trackers)
  • Cryptominers
  • Fingerprinters

I guess that is the same as the "Strict" setting, but with custom it feels easier to control with more granularity, and to set exceptions etc.

Next, under the "Security" section of the Privacy & Security page, you should ensure you have all the boxes ticked.

Search engine

Finally, under the Search button you should go and change your search engine from Google. I would suggest having DuckDuckGo as your default search engine. Personally I'm using a service called YubNub, and have done so for years, but that is possibly basis for another article I guess. Basically YubNub turns your address field in your browser into a fully functional command line, which can be very handy for someone like me, but probably is overkill for most of you.

The search engine I'm actually using for internet searches, via YubNub, is indeed DuckDuckGo, as it cares about your privacy. Protecting your privacy is even the unique selling point for DuckDuckGo, who will not track you or your search history in any way what so ever.

More advanced

For the next thing on the list you need to open up a new tab in your (Firefox) browser, and type "about:config". It will ask you if you are totally sure. You (hopefully) are so you say yes. You will see a long list of configuration settings.

Now we are going to disable the WebRTC, which basically stands for "Web Real-Time Communication". It might sound like a good thing, but it basically enables real-time without any additional plug-in. The cost of doing so is that it reveals your actual IP address, even if you are on a VPN which might have given you a "hidden" IP address.

In the search bar at the top, type in "media.peerconnection.enabled". It will filter down that list to only show you one line of text. If the "value" says "true", double click on it and it will say "false" instead. You can test this setting over here: www.perfect-privacy.com/en/tests/webrtc-leaktest to see if you've enabled it correctly. Basically it should not detect your IP-address under that test.

Installing Facebook Container add-on

Facebook - Barred
Facebook - Barred

Firefox has an add-on called "Facebook Container", which you wish to install. This add-on does a great job in ensuring Facebook can't track you on various sites as you go about shopping, browsing or doing things that you normally don't associate with Facebook, but where those little "log-in with Facebook" or "share to Facebook" buttons are. As soon as this add-on detects links going to Facebook from a site, it will put that link behind "bars" and disable it. You can, if you wish, enable it to function normally, but if you don't, Facebook will not get notified of you even being on that particular site. This add-on is created by Mozilla, the creators of Firefox.

Installing ad blockers and tracker blockers

After that you wish to install the following add-ons too:

Ghostery is created by Cliqz, which has a whole host of privacy related solutions, and Privacy Badger is created by EFF, which stands for "Electronic Frontier Foundation" and is a well-known actor in the space of protecting the privacy of end-users online within a multitude of areas.

Basically these plugins are blocking various trackers and tracker scripts, and they are pretty much just "install and forget" type of add-ons. There can be instances where you notice a particular web site is not working due to extensive blocking of various scripts, but in those cases it is simple enough to just click the little icon in your browser and enable that particular script to run. It hasn't happened a lot for me, and I probably browse more things on the internet than most. More importantly, it puts me in control over when I will allow certain tracker scripts and/or images to load.

Badges
Badges

Another thing you should install is a "regular" ad-blocker. I have opted to go for uBlock Origin. There are others, but some of the others have been criticized for collecting data, or for allowing some advertisers but not others etc. I have, so far, not found any similar information regarding uBlock Origin, and thus has opted to use that.

By now, if you've installed all three of these add-ons, you will have three icons to the right of the address bar in your Firefox browser. Those little icons will highlight when they are working. On this particular site you will notice they say "0" in their little notification bubbles. That means this web site has absolutely no tracking and absolutely no advertising on it.

If you wish to see the three plugins work really hard I suggest you go to Swedish newspaper Aftonbladet.se. When you get there those little notification bubbles with show completely different numbers. As I'm typing this I notice my window in the background, on which I went to aftonbladet.se, currently is up to 16 scripts blocked by Privacy Badger, another 3 scripts have been blocked by Ghostery, and 34 ads have been blocked by uBlock Origin. When I scroll down that page just a little bit, uBlock Origin indicates it has blocked 89 (!) ads, and it is still ticking up steadily. That is over 100 requests (!) to servers that has been blocked. Also, the add-ons have blocked you being tracked, so whatever you do on the site will not follow you around when you continue surfing the web elsewhere. Good stuff.

Install HTTPS Everywhere

Another add-on you wish to install is HTTPS Everywhere. It does pretty much what is says on the tin: it creates all your requests to web sites over HTTPS, where the "S" in "HTTPS" stands for "Secure".

When your browser tries to access a web site (for example https://wikipedia.com) your browser makes a series of "hand shakes and introductions" to various internet servers. The only way to ensure that any of those handshakes are happening with the correct server is ensured by certificates that are tied to their URL and IP addresses. If your connection happens over HTTPS you will have a much stronger guarantee that the site you think you are visiting truly is that site, and not a site that has been "impersonated" (or whatever the equivalent for web sites are), pretending to be someone they are not.

HTTPS Everywhere basically ensures you are truly using the HTTPS protocol at all times and that the site you think you are visiting truly is that site, and that it hasn't been "spoofed".

Install your VPN providers add-on

This is assuming you indeed have a VPN provider, which you should. In my case I use NordVPN, and they have their own add-on called NordVPN Proxy Extension. For NordVPN I also have an app installed on all my machines/devices, enabling me to connect the device as a whole to VPN (meaning any and all connections will go through VPN), but sometimes that isn't needed (when you need to use other services on your local network for example). With the add-on I can be connected to my regular network if I wish so, and still enable Firefox to connect via NordVPN, separately.

So far so good...

By now you have massive improvements in securing your Firefox browser compared to how it was. An added bonus is of course also that it isn't a browser made by Google, which means Google and its advertising network, are in your control now as far as tracking you and showing you ads go. You now will be protected from any and all tracking and advertising scripts. If you are on a VPN you will not be able to be seen on your original IP-address either, and your browser will not be "leaking" personal data. You are now massively better off.

But don't just trust me on this, test it out for yourself. Ensure you have everything enabled, and then you go and re-read a previous article I wrote on checking how much data you might (or could) be leaking. If you did that test previously, or if you'd like to do it now in another "non-secured" browser such as Chrome to compare with, and you can now marvel in wonder at how different the results will be in your Firefox.

That is sort of it when it comes to securing your Firefox browser.

But wait, there is more!

There are a couple of things you still can install that perhaps is not crucial for security/privacy, but that can be very helpful indeed when surfing around on the internet. Further to the add-ons above I most often have the following add-ons enabled as well.

F.B. Purity and Stylish
F.B. Purity and Stylish
  • F.B. Purity - This add-on makes Facebook bearable, as it allows you to completely customize Facebook in your browser. Wish to remove ads? Done. Would you like to see your "News Feed" in chronological order instead of what Facebook has chosen for you? Simple. Wish to not see "suggested friends"? Easy. Do not like to see stories? Check a checkbox and they're gone. Don't want the right-hand side bar? Just remove it. This add-on is so effective that Facebook has banned its link/URL to be posted on Facebook, as it disrupts their money flow too much, but Facebooks money flow is hardly my concern.
  • Burner Emails - lets me quickly create a fake email address for sign-up forms when needed.
  • Cookie Quick Manager - To delete cookies from a specific site easily. This can be very handy, especially when used in conjunction with the add-on below, as it can remove all those "you have viewed 2 out of your 3 free articles this month" kind of messages some sites use.
  • Firefox Multi-Account Containers - This basically extends the containers described previously in this article and will let you create your own containers for various things. For example you could put all newspapers that use cookies to regulate amount of articles you are allowed to read in a container you've named "Reading". You can then force those web sites to always open up in that container, which you in turn ensure you always delete cookies in before closing that tab, so it is always "fresh". The "Multi-Account" part in the name also indicates another benefit: you can be logged in to the same service multiple times if you have multiple accounts for a service. This would otherwise be impossible, as your browser would "know" you are logged in with one specific account, and it can be tedious to open up new "private" tabs all the time and keep logging in.
  • I don't care about cookies - This will remove all the messages saying "we are about to set a cookie, do you agree?" messages. Despite the name of this add-on I do care about cookies, but it is a fact that pretty much all sites (except this one) will set a cookie, and don't need a message about it beforehand and I most definitely don't need to press "agree" on it for every site. It will be set. I will delete it afterwards if I choose to (with the Cookie Quick Manager, above).
  • Greasemonkey and Stylish - These two allow you to add your own custom code to any site, provided you know how to code for the web, though there are also ready-made code snippets that you can download if you don't know how to code. You can for example increase the text size of headlines on a specific site, or you can change the entire colour scheme on another. I run a Stylish script for those rare occasions I go to Facebook which makes Facebook dark. On another forum site I run a script to highlight which posts I've read (they are dimmed) or which posts are new (they get another colour), etc.
  • LastPass - LastPass keeps track of all my passwords, on all my devices and in all my browsers, so I don't have to.

That is it

Given the amount of time we spend in our web browsers when we are using our computers, this is well worth doing. The aim with this is to inform you on how I took control over my own data, and when I share what. It is up to you to do whatever you think is correct/right for you to do.

It can be noted that most of these add-ons (also called "extensions" in some browsers) are available for other browsers, even Google Chrome. That is true. However, as long as you are logged in to Google Chrome with your Google account, Google will always be able to follow you around, regardless of what extensions/add-ons you install. Your browser will send your browsing history to Google, along with everything you type into Google Search (which is the main reason you should be using Duck Duck Go for searching ever after).

I have all the above set-up for Vivaldi browser too, which serves as my secondary browser these days.

Also, do remember to get a VPN provider (NordVPN in my case) as well as a Password manager (LastPass in my case), if you haven't already.
