Privacy Addons

uBlock Origin

firefox addons 9

The first must-have extension; It’s an open-source Firefox addon that blocks advertisement scripts on the Internet, which would speed loading the website your browse (since your browser won’t have to deal with them any longer because they are blocked). Those scripts usually also violate your privacy, so it’s good to block them in general. Just remember to unblock the websites you think have a reasonable usage of those scripts.

Privacy Badger

firefox addons 11

A famous addon to block tracking scripts, which try to collect some of your personal information and browsing habits and send them to the websites owners or other 3rd parties. Extremely useful in preventing this from happening, and it also shows you the tracking scripts that are loaded on the page, with the possibility of unblocking them if you want.

HTTPS Everywhere

firefox addons 13

HTTPS is the encrypted, safe version of the HTTP protocol, which is used in communication between your browser and the websites you visit. Some website do offer HTTPS version of their service, but they don’t use it by default. This extension solves this problem by ensuring that everything is loaded over HTTPS wherever possible.

You can also choose to block all the non-secure HTTP protocol communications if you want from the addon’s settings.

Link to install the addon:

Cookies AutoDelete

Cookies are simple text identification files that get stored on your computer whenever you visit an Internet website. Cookies can be useful so that you see content related to your preferred tastes/behivours or browsing history, but research has shown that cookies can be also easily used to identify you and your web browsing habits across the Internet.

This Firefox addon simply solves the issue by auto-removing cookies whenever you close the tab assosicated with it; If you watched some videos about “Linux” on YouTube, and then closed that tab, all YouTube cookies will be auto-deleted instantly so that if you open YouTube again, you’ll see a “fresh” version of it that doesn’t recognize anything that you have done before on the website (Even if you logged in, it will instantly log you out if you close the tab).

Just make sure to enable the “active mode” in the addon’s settings and set the time to 1 second:

Comments to: 15 Firefox Addons To Consider Using Right Now
  • February 11, 2019

    These look like a lot of the things that were built-in to the original Opera Browser. I still miss it everyday

    • February 11, 2019

      Why do you miss it? You can download and install Opera anytime you want, no?

    LastPass and Grammarly are not FOSS, they are using users data.

    BitWarden is a free and open source password manager, you should at least change that recommendation.

  • February 13, 2019

    The fact that LastPass and Grammarly are using user’s data is not what makes them not FOSS. Mozilla and Chrome browser also collect users’ data, although they do request this from time of installation, and one can opt out. Password managers that keep your data in the “cloud”, are particularly not well-suited for FOSS. When a customer pays LastPass they have extra legal rights in the US (where LP is based). If a small organization offers to save your passwords (extra-locally) for free, they are suspect. Perhaps Mozilla will continue to evolve password management (as Chrome has with Google), but until then LastPass is appropriate. As far as Grammarly, I do not think there is an equivalent FOSS service or app. Both these extensions are presented specifically for Firefox, which is FOSS. I think they deserve inclusion on this basis. Excluding such useful services when there is no viable FOSS alternatives would be short-sighted. I would suggest reading the history of the term “Open Source”, and why it became widely adopted over Stallman and FSF’s rigid definition of “Free Software”

    You really should try OneTab and Multi Account Container.
