Firefox is a browser by Mozilla that is friendly to non-technical people, while providing power users the ability to tweak it to their likings. I myself use it most of the time, only opting for Chromium-based browsers (like Vivaldi) when the website won’t function on Firefox and its forks. (You can blame Google for that)

Today, I’ll be giving you all the tweaks I’ve come across, and tweaks I’ve done (some recently). Most of these won’t be beginner friendly.

Disclaimer

I’m not an expert on this subject matter and is merely sharing my knowledge based on what I know and what I have done. Be sure to follow reasonable advice and backup your firefox profile.

I assume you have enabled basic tracking protection on Firefox’s Preferences menu and have some knowledge on fixing or getting help when things go wrong for you.

Addons

Despite minimalism being a good factor for privacy and security (less attack vectors), according to TheHatedOne on Youtube, I use quite a lot of addons for Firefox. These are:

Multi-Account Container

A very helpful addon that lets you compartmentalize your activities in separate containers. You can use one container to use for your Personal online activities, and another for your other online activities (like Googling or Ducking keywords).

Simple Tab Groups

Another helpful addon that lets you group your activities in separate groups. The addon is very much compatible with Multi-Account Container. This alone won’t separate trackers from tracking you, but if tweaked and configured well, you can use it with Multi-Account Container to separate your online identities and provide you with better user experience than just using each addon on their own.

UBlock Origin

A very helpful blocker addon that lets you filter many things that connects to your browsing session. You can set it to Advanced User mode and make it block things like 3rd party connections and javascript, as well as fine tune settings for specific websites for better experience. Remember that all these things are for the long run, so the longer you use and configure UBlock, the better and smoother future usage you would have on your usual sites.

Cookie Autodelete

If you haven’t configured Firefox to automatically delete cookies and data on exit due to convenience or site requirement, Cookie Autodelete might be for you. It automatically deletes cookies of sites you have visited and left (under a time limit, default 15s). You can also exclude specific sites from having their cookies deleted.

First Party Isolation

If you have heard of about:config and seen some settings, you might have also come across Firefox’s privacy.firstparty.isolate setting. If you have websites that won’t properly work because of first party isolation turned on (learning sites, et. al.), and if you don’t want to keep opening about:config and setting the config on and off, this addon might be good for you.

HTTPS Everywhere

I should have placed this higher in the list but it’s the usual addon recommended, and you probably don’t heed its warnings and open non-HTTPS sites anyway. Make sure you have turned its EASE mode on and practice online safety and security well by avoiding non-HTTPS websites.

Decentraleyes

A plugin that uses Decentraleyes’s CDN network to give you their local CDN libraries instead of others. This provides a layer of privacy from common CDN providers and is a nice addon to have. Although I don’t know how significant the addon provides for protection, it is still a nice addon to have just in case.

Privacy Badger

An addon that automatically blocks third party trackers based on whether or not that tracker has been spotted from other sites you visit. Nothing much to say about this, since it’s meant to be set and forget. It’s a nice addon if you think blocking everything with UBlock is lacking and needs more backup backup backup blocking.
