These aren’t unknown things. Airports are taken very seriously, and they work closely with regulators.
But especially when you’ve worked in a high reliability airport, you can’t help when you travel to others and notice where they’re falling behind, things they haven’t done yet. Etc.
If the Firefox thing is a real pain, do consider the librewolf project, since it won’t save your session every time, but also has ublock origin already set up by default.
Remember that even if you’re unsure some software is for you or not, just try the flatpak. One command to install, and one command to remove if you didn’t like it. Because it’s containerised you don’t need to worry about it leaving behind unused libraries or cluttering your system with leftover bits.
