I’d like to add that you can setup desktop shortcuts pretty easily for Mullvad and TOR browser manual installs. For TOR browser simply run this after opening a terminal in the folder it was extracted to:

./start-tor-browser.desktop --register-app

Same thing should work for mullvad.

It is the default atime option used when mounting if I’m correct. If it’s an ubuntu specific mount option it will be specified in /etc/fstab file.

You can run this to check

findmnt --real

I actually use both in fish. I use aliases for some longer commands. For example I have la as an alias for eza -la --icons=auto --group-directories-first because I don’t really want to see it every time I run la. I use abbreviations for some shorter commands. For example systemctl abbreviated to sys and systemctl --user abbreviated to sysu.

I use Firefox as my main browser. I use the multi-account containers extension in Firefox to seperate my browsing activities. Brave is installed as a backup in case firefox fails me. I use TOR browser for searching for stuff that I don’t want linked to me.
