The Firefox Android app on Chrome OS [B]
Overview [B]
I want to start with the Firefox Android app. You can install it from the Google Play Store. Do you’re a Chrome OS beginner, and only the browser’s core functions are essential to you? Then this app will be enough for you!
The installation [B]
The Chrome OS’s launcher lets you search for the Play Store and launch it from there:
There you search for Mozilla Firefox and press the Enter key:
Click on “Install“ to install the app:
How to use the Firefox app
Once the Firefox app is installed, you can find it in the Chrome OS launcher:
When you start the app, Firefox first offers you basic options for privacy, design (light/dark), and toolbar location (top/bottom):
If you confirm your selection with “Start browsing,” a simple view appears that allows you to browse websites:
Is this limited functionality not enough for you, and you don’t want to miss out on any of the features you use in the Firefox on Windows or macOS? No problem! That’s also possible! 🙂
The desktop version of Firefox in Chrome OS Linux mode [A]
Overview
There is a Linux version of Firefox that brings a similar feature set as Firefox for Windows or macOS.
In the package sources of Debian Buster, the Linux distribution of the Linux mode of Chrome OS, Firefox is included as Firefox ESR (a version with extended support), which is based on an older version. You can download and install the latest version from the manufacturer’s site. I describe both versions here.
How you can activate the Linux mode and configure a different language as system language, I have described in this post: Link.
The installation [A]
With a graphical app store [A]
In this post, I described the Gnome Software Center: link and here the KDE Plasma Discover: link. Which software management you want to use is a matter of taste. I describe here the installation of Firefox using the Gnome Software Center. The installation via Discover is similar.
Search for Firefox in the Software Center search box:
Then click on the search result “Firefox ESR.”
You start the installation with the button “Install:”
That will install an English version. If you want to use Firefox in a different language than English, you must install the corresponding language package. To do this, start the “packages” application belonging to the Software Center.
There you search, e.g., for “firefox-esr-l10n-de” for the German language pack:

You may change “de” to “fr” or “es” for another language like French or Spanish.
Using Firefox [A]
After the installation, I recommend you reboot your system and then start the terminal or another Linux application.
Once this is done, you can find Firefox in the launcher and launch it from there:
If you want to learn more about Firefox, feel free to leave a comment. 😉
Via the terminal [P]
First of all, you should update your system and applications:
sudo apt-get update && sudo apt-get upgrade
Now you can install Firefox, including, e.g., German language packs:
sudo apt-get install -y firefox-esr firefox-esr-l10n-de*
You may don’t copy the last part of the command if you want to have the English version. Alternatively, you may change “de” to “fr” or “es” for another language like French or Spanish.
The latest version from the manufacturer’s site [A]
Here you can download the latest Linux version of Firefox: link.
You may save the packed version in a folder of your choice. I always recommend a folder below “Linux files.”
You can unpack Firefox, e.g., with the Double-Commander (described by me here: link):
Then confirm everything in the dialog that then appears by clicking on “Ok:”
Double-click on “Firefox” to launch Firefox:
At the moment, I don’t know how to create a shortcut for it in the Chrome OS launcher. That will follow in due course.
Conclusion
You are free to choose your browser on Chrome OS, also. Firefox can be installed in different variants and can be used similarly to Windows or macOS.
Have fun with it! 🙂
