Thoughts from my 14-year-old backup Thinkpad T430 after the main laptop died:

* Github's javascript UI is SO SLOW
* Most of the rest of the web is actually not terrible (at least with adblock)
* It drives a 4K screen surprisingly well
* Video playback is bad
* How is this thing running out of RAM, it has 12GB...
* The keyboard is a delight

So it turns out that Ubuntu's Firefox Snap blocks Firefox from reading the system memory pressure, which it uses to work out when to reclaim memory by hibernating unused tabs.

Nobody thought to check why this kept getting blocked by AppArmor until someone pointed it out, and it still hasn't been fixed.

@russss snaps are why I left Ubuntu woth zero regrets.

@janl @russss using what now? Debian?
Went for Ubuntu in, what... 2006 because "bleeding edge" compared to debian.

Must say, I'm starting to like fedora on my laptop more and more

@miekg @russss a mix of Debian and FreeBSD.
