From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Nothing special, I don't think that's the problem since the lag is at every launch and it takes something like a minute to appear.
It also happens when the hosts file is messed up and the system can’t resolve its own hostnames. Opensuse used to be pretty notorious for doing something odd to the hosts file by default that really only affected Firefox.
Edit: the increased security they’re trying around the browser might also be triggering that local resolution issue
Listen to the parent, this is almost certainly something to do with DNS (i.e. Firefox is not getting an answer for some reason, then timing out, then using maybe a backup DNS server; maybe there are multiple rounds of this). Who knows how your distro and that flatpak produce this interaction, but something is going on there.
If that's the issue, why it doesn't happen with all other flatpaks?
Don't know. Different runtimes? Different permissions?
