That is an issue with GNOME Software on Debian based installs, firefox-esr shows as the old icewaesel
From the command line install the packages: firefox-esr and firefox-esr-mobile-config the last one includes tweaks to make firefox fit better in a mobile screen.
At the moment we are missing an image viewer that is adaptive.
If you want to take screenshots, you can install from the command line the package: librem5-goodies it contains the application that @Kyle_Rankin made to take screenshots. After install it will show in the app tray as: Screen Shot
Why did you do that? Why root access must be locked? So many years on Linux systems I am used to su. Why should I get used to something else? Can one bring root access back?
The pureOS version on the Librem 5 is based in Debian stable, with an overlay layer for some packages. There are some packages that will be fast forwarded. And soon it will be based in GNOME 3.38
This is what I assumed and am glad is the case. It wouldn’t make much sense with how much one needs root access to have that functionality locked away. I think having it set like this though helps many people, who have never used Linux to not accidentally hose their L5.
So far the L5 really seems to live up to the general-computing device in your pocket moniker. I’m super pumped.
