More for fun than being really useful, here’s a little tutorial on how to use Firefox on Chrome OS (Flex) (for me, it’s currently version 100 in the Dev Channel). But beware, the user experience really leaves a lot to be desired…

1. Enable the Linux environment
2. Open a (Linux) terminal
3. Install Flatpak and add the Flathub repository
4. Install Firefox using Flatpak: flatpak install org.mozilla.firefox
5. In Chrome, open a new shell using CTRL + ALT + T
6. Type vsh termina (Read about Termina here – a VM image with a stripped-down Chrome OS linux kernel and userland tools)
7. Type lxc config set penguin security.nesting true (this allows the default Linux container penguin to run containers itself – it is somehow required)
8. Restart your computer
9. Open Firefox

I really have to take a closer look at the architecture of Chrome OS or Chromium OS, the structure with all the containers sounds interesting. This reminds me of Jessie Frazelle, who at least a few years ago, only used containers on her desktop…
