Testing HTTPS clients using openssl to simulate a server
This article describes how to test your HTTPS client or browser using openssl. To test your HTTPS client, you need an HTTPS server, or a web server, such as IIS, apache, nginx, or openssl. You also need some test cases. There are three common failure modes in SSL/TLS:
- The client makes the connection when it should not,
Protect Your Online Privacy With The Tor Browser Bundle
For anyone looking to protect their privacy online, Tor is an invaluable tool. It is both one of the most reliable ways to hide your identity and one of the easiest to use on Linux.
Tor works by routing your computer’s internet traffic through their own network. This way, you can still access online resources as usual, but your network traffic appears to originate from the Tor network, your IP address remains hidden, and your data is encrypted in the process. With Tor, you can also access .onion domain names, and access the infamous dark web.
In this guide, we’ll show you how to download, install, and configure Tor on a Linux system. This will get you up and running in a few steps so you can anonymize your traffic and access Tor-specific websites.
In this tutorial you will learn:
- How to download and install Tor on Linux
- How to configure Tor
- How to keep Tor up to date
- How to install new addons in Tor, and should I?

How to install Chromium web browser on Linux
Chromium is an open source browser maintained by Google. Along with the Chromium browser itself, Google Chrome, Microsoft Edge, Opera, Vivaldi, and a slew of other notable web browsers are all based on the Chromium source code. It’s safe to say that Chromium plays a huge role in the way that many users view the web today.
Despite Chromium’s influence, it’s far more common to see Mozilla Firefox as the default web browser on Linux systems. Chromium is still the default browser on some systems and is almost always able to be installed directly from a distro’s package manager. Contrast this to a browser like Google Chrome, whose closed source precludes it from being as easily installed on Linux.
While Chromium is a fully functional browser on its own, it’s missing support for propriety codecs like H.264 and AAC. At the cost of minor inconveniences like this, you’ll be getting a open source, Chrome-like browser. We dive more into this topic in our Firefox vs. Chrome/Chromium guide.
In this guide, we’ll see how to install Chromium on all major Linux distributions.
In this tutorial you will learn:
- How to install Chromium on Debian, Red Hat, and Arch Linux based systems
Firefox vs Firefox ESR on Linux
Mozilla Firefox is a really popular browser to use on Linux systems, with many or most distros even including it as the default web browser. It even edges out Chrome and Chromium, at least in the Linux world.
Some Linux distributions, like Kali or Debian include a different version of Firefox, called Firefox ESR (Extended Support Release).
In this guide, we’ll be comparing Firefox to Firefox ESR. This will include a look into why some distros come with ESR instead of the normal version of the browser, and also what the pros and cons are of both browsers.
In this tutorial you will learn:
- What is Firefox ESR?
- Why do some distros use Firefox ESR?
- How to download Firefox ESR
How to install Opera web browser on Linux
Opera is a web browser based on the Chromium project. While not as popular as Mozilla Firefox or Google Chrome, it has been around a lot longer than both of them and offers a great web browsing experience with its sleek user interface.
Although it’s based on an open source project, Opera developers include their own closed source and proprietary additions in the final package. This is frowned upon in the Linux world, which means that Opera is almost never the default browser on a Linux distribution. Furthermore, it may not be included in official repositories, so it can’t even be installed (by default) with a distro’s package manager.
Despite this, it’s not hard to install Opera on a Linux system. You just need to follow a couple extra steps. In this guide, we’ll show you the step by step instructions for installing the Opera web browser an all popular Linux distributions.
In this tutorial you will learn:
- How to install Opera on Debian, Red Hat, and Arch Linux based systems
Firefox on Linux – Your connection is not secure
When browsing the web, your computer can communicate with websites through two different protocols: HTTP and HTTPS. HTTPS is the safer version of HTTP, with the “S” standing for “secure.” Whether a website is configured to communicate with its users securely or not is up to the site administrator.
On certain websites, you may notice Mozilla Firefox or another modern browser indicating that “your connection is not secure.” This basically means that the website is using HTTP instead of HTTPS. Whether a site is using HTTP or HTTPS will always be indicated by the padlock symbol next to the URL of a site.
In this guide, we’ll go over this security warning, talk about the seriousness of it, and give some tips for how you can protect yourself when browsing the web with Firefox on a Linux system.
In this tutorial you will learn:
- Why are some sites still using HTTP?
- Why is it important for sites to use HTTPS?
- What can I do to protect myself when browsing a site with HTTP?
How to improve Firefox font rendering on Linux

Firefox with VA-API on Linux
The Video Acceleration API, developed by Intel, has been enjoying widespread support in a variety of software, including the latest versions of Mozilla Firefox. The VA-API is an API for hardware acceleration that allows a computer to offload video decoding and encoding tasks to a system’s video card, a task that historically has taken place in the CPU.
In this guide, we’ll talk about Firefox’s VA-API setting. This will include a brief introduction to what it is and how it works, as well as how to enable or disable the setting on a Linux system. Keep reading if you want to give the VA-API setting a try, potentially speeding up your web browser’s video playback a great deal.
In this tutorial you will learn:
- What is Video Acceleration API in Firefox?
