Neat. Turns out that https://addons.mozilla.org/en-US/firefox/addon/enterprise-policy-generator/ is a pretty nice frontend for generating configuration to feed to https://mozilla.github.io/policy-templates/

Why would you want to? Because it allows you to force load from the side a set of preferences and extensions. For your own use, or give to others.

Also, works great for #QubesOS #DispVM config where the VM gets recreated every time 😂

#FireFox #Privacy #InfoSec

Fun fact about #QubesOS (at least R4.3 release candidate) – seems like if I *log out* of the desktop environment session and then log back in all my stuff is still running, and GUI apps' windows show up just fine.

Which makes sense, the VMs have no reason to shut down just because KDE or whatever is not running anymore.

But still, it was a "huh!" moment when I noticed that!

Next I need to test if that's true also *between* different desktop environments (say, log out of KDE, log into Xfce). 👀

yet again I needed to download and verify a @QubesOS image, and yet again having the QubesOS official t-shirt (which has the Qubes Master Signing Key fingerprint printed on it) turned out to be very useful, actually.

I am such a nerd.

Related: is anyone using #QubesOS with a 4k 14" laptop screen?

My experience is that QubesOS does not support UI scaling very well, so having a 4k screen might cause annoying issues. Especially with external screens.

I'd love to hear from anyone who is using this kind combination. :blob0w0:

Edit: brainfart, I meant 4k, not FHD 🤦‍♀️

Time for a new laptop, my trusty Thinkpad T490 is getting a bit long in the tooth.

It served me very well 6 years or so. My previous laptop served as my daily driver for roughly the same amount of time.

I like doing research and getting a device that I don't have to worry about for half a decade.

And on that note, I am looking at two #QubesOS certified laptops:
