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.

It usually does that for me when the XDG Desktop Portal borks. Run it from a terminal (flatpak run) and see if it complains about not being able to find a "settings" portal. You can also try to restart the xdg-desktop-portal.service user unit.
No joke, XDP has been so fucky on Hyprland, I have a keybinding to restart it.
I tried restarting portal, didn't work. systemctl status for xdp did show an error for hyprland about a config file. But I'm running on sway mainly. I just tried out different DE's to see if anything changed.
Here's flatpak output

That's more or less what mine says. What about journalctl, does it print anything in red?
Nope it's all green.
Idk if you saw my update but turning of the wifi fixes this problem.
I did move to a new network yesterday, I just didn't think that could impact the flatpak launch, while not affecting the systems binary launch.
It's a real head scratcher
What brand and model is your wifi card? Linux has always had issues with Broadcom modules, but I don't know why or how that would affect flatpak. Maybe you can find a relevant permission in Flatseal (like allowing the browser to control the wifi card) and turn it off for Firefox.
The card is Realtek. I found an askubuntu thread where all flatpak commands were hanging, and their solution was to disable the nic.
This has only happened on this network. I didnt mention at first because I didnt think it mattered, but I'm visiting someone and moved networks.
The instant I take the dev down, the browsers pop up. I would bet money that when I go to my home net everything will work.
The flatseal angle didnt work either. The only reference is names on system bus.
Sometimes some programs and some downloads have weird slowdowns like this when my VPN is on, even though others remain completely unaffected
All vpn things are off (i.e. wireguard and tailscale)
What version of xdg-desktop-portal-* package do you have installed? If it's -gnome try replacing it with -gtk, see if that helps.
The gnome portal is not running. The gtk and wlr portals are, as they have been for months with no issue.
xdg-desktop-portal-wlr.x86_64 0.7.1-1.fc39
xdg-desktop-portal-gtk.x86_64 1.15.1-1.fc39
But is the gnome portal installed? Firefox may still try to use it if it's there.
You don't lose anything by uninstalling the gnome portal, the gtk portal takes over.
I uninstalled, it didn't change anything :(
Could you leave journalctl -f running while Firefox is starting? Anything interesting happening right after initiating the start and/or before it actually starts?
The only thing that came up was some memory allocation/cgroup/.slice stuff for the container.
I'm not on that network anymore, and the problem is gone. So I cant reproduce.
Maybe I should have run wireshark?
I mean, you could, sure.
As a next sensible step though, I'd start firefox from the CLI with more verbose logs enabled.
Also a dbus notification daemon (whichever you use) may be having problems. Things hang inexplicably if it's not running.
I'm using dunst and it's running. I dont get notifications often, so I opened element to get some. Element isn't working either lol
I'm also having this issue on my desktop with Firefox flatpak connected via Ethernet and Librewolf deb on my Surface Pro 8 via WiFi. On the SP8 it opens immediately on disabling WiFi or switching off my VPN which seems bizarre but at least partially lines up with your experience.
I'm an uninformed casual on Linux but if I can help diagnose/resolve this lmk
You could try dmesg -w in a terminal before you start firfox and see if any messages come through.
Can you still access the internet with another program?
This could be a firefox issue, and not a flatoak issue as I assumed. Do you have another version of firefox on the system? If so what version?
They all look to be 123.0, though bizarrely the version advertised as flatpak in About Firefox doesn't pause/delay before opening but the other version does. No messages come through on dmesg -w unfortunately, I'm pretty stumped. The only clue I have is that the version of Librewolf I have on my desktop installed through the Pop Shop doesn't delay opening but the same version on my SP8 installed through deb does.
Ultimately it does point towards FF in show way?
I noticed that as well. I don't know why and it seems very random. It happened on my virtual computer with a AMD GPU but my laptop seems unaffected.
Install perf and use the app hotspot or just perf itself to run the command and see what happens
Good old flatpak. Based on this you can expect it to take roughly thirty thousand years next time you need to restore a system backup.
I've been considering switching to Linux, but did you say Firefox takes 30 seconds to start? Is that standard? Edit: what a strange bunch you are to downvote a random question.
No, it opens without delay.
Yeah I am on a potato, i just gave that as a reference. Its really probably more like 10 the first time it opens. After that its faster.
Excellent, thank you.
Non-sense, any linux, even the most wasteful in resources, ubuntu, mint, manjaro, debian, fedora, gnome plasma DE, uses a fraction of resources to start and execute whatever. I have 2-3 friends running daily on early/mid 2core intel/amd machines where w10/11 wouldn't even boot!
