Unmounting does not mean the device gets invisible. You could still mount it again by e.g. clicking it. Still it is unmounted and safe to be removed. Disconnecting the device from the system makes it disappear but that is not required for unplugging/ejecting.

This would be a flight mode switch that reliably works. But it also means you are offline, which is no solution to the average “daily” problem of being tracked.

As much as I would love to have a Linux phone, it will not fully help with privacy. The devices are logged into a cell tower and have a unique ID. This alone makes them trackable.

It is not worthless. My understanding is that management only trusts sources that are expensive.

Which version did you try? I used the 24.12.something version earlier this year for some rather complicated project and it was very stable.

I know they had stability issues before but not with that version. Disclaimer: I did not do video editing since, so I cannot say if the stability issues are back.

Do you mean sandboxed?

Unfortunately Mozilla is going the enshittification route more and more. Or good in this case that the Firefox Phone did not take of.

Nice. Have fun with it!

Agreed. My answer was in the assumption that it’s about desktop apps as the OP mentioned Electron.

I think I heared that lan-only mode means you need to transfer the files to print via SD card.

Go with one of the ready to use systems. Flatpak, Snap, AppImage. Snap is largely Ubuntu Ecosystem, Flatpak is independent. AppImage is an option if you do not need/want a Sandbox.

Stay away from Docker and LXC for this use case (graphical applications), they are much more work to get going.

I have some Sandy Bridge systems here running strong as Linux desktops for light work. You know, these 4-core 3,3GHz processors from - hmm - 2014?
