I am trying to follow the guide linked to install Firefox on an older Chromebook. It looks like the device should be supported, as running the command cat /etc/os-release returns that it is version 10. When I get to step 4 and try and run that I get a permission denied error and later steps do not work.

I did try the Google play option on the Chromebook, it says the device is not supported.

Firefox was my default browser until I had to install Microsoft 365, which I think is repeatedly blocking my attempt to restore Firefox as my default browser. Every time I try to download it stops two-thirds of the way through.
