Bonjour,
Since last update, my firefox and thunderbird are going more and more slowly: they take 3 mn to start, when I click on a link in a mail it takes about 2 mn to get it in firefox (which is already started).
firefox 137.0 thunderbird 128.9esr
What is the problem?
Thznk you.

I don't use Thunderbird, but the usual advice with browser problems is to restart with all extensions disabled (e.g. 'firefox --safe-mode') and see if it makes a difference. If it does, then enable extensions one by one (or using a binary bisection) until you find the culprit.

I'm in Nova Scotia. Normally, many apps use European mirrors via cross-Atlantic cables. I've seen issues recently thatI suspect are due to the Iberian Peninsula power problems.
The problem could be network, graphics, or resource constraints (memory, mass storage, rogue processes hogging CPU) , or a configuration problem. There may be useful details available from `journalctl`.
You should provide enough detail to allow others with similar configurations to reproduce the issue/. The output from `inxi -Fzxx` would give us an overview of your hardware.
Try creating a new user account with default settings to rule out some configuration issue with your account. Linux has many tools that show you resource utilization. Your graphics environment probably provides some GUI tool. `top` should be available in a terminal. I have found bpytop useful.

You can run traceroute to see if that's happening, though it seems unlikely.

I was thinking of this but I don't know if I will understand the messages. I'll try tomorrow.
Running firefox --safe-mode (as you suggested, but nothing has changed) I got this message:

Possibly something in your graphics stack. Is your GPU driver up to date? Also, As Tim says, have you rebooted your system after recent updates, especially if drivers and/or libraries have been affected?

Of course I rebooted the machine after update.
As fotr the GPU driver I use the Nvidia driver from rpmfusion repo and I suppose that during every update akmod does its jobs... How to be sure?

If you don't reboot too early it should work yes.
How to be sure?
For example like this:
1. glxinfo -B
Should show something like:
OpenGL vendor string: NVIDIA Corporation OpenGL renderer string: Quadro K4000/PCIe/SSE2 OpenGL core profile version string: 4.6.0 NVIDIA 470.256.02
2. lsmod | grep nvidia
nvidia_drm 86016 8 nvidia_modeset 1511424 3 nvidia_drm nvidia_uvm 2834432 0 nvidia 40759296 84 nvidia_uvm,nvidia_modeset video 81920 2 dell_wmi,nvidia_modeset
3. modinfo -n nvidia
/lib/modules/6.14.2-300.fc42.x86_64/extra/nvidia-470xx/nvidia.ko
4. dnf list --installed kernel kmod-*

I tried this morning, the process stops twice for a while on this message:
recvfrom(8, 0x7f319d163000, 131072, MSG_DONTWAIT, NULL, NULL) = -1 EAGAIN (Ressource temporairement non disponible) ppoll([{fd=8, events=POLLIN}], 1, {tv_sec=119, tv_nsec=999910000}, NULL, 8
Who can tell me what does it mean?
Thank you.

I'm going to ask the obvious: Have you rebooted since the update?

Hmm, just looked at some of that, there was a bit of a how to tie your shoelaces feel to it.

The problem seems to be linked with "systemd-resolved.service" for, if I disable this service the problem no more occurs. But I have no dns!
Is it impossible for firefox/thunderbird to live with systemd-resolved.service ? (chromium has not this problem, but I don't like google) Or something is missing in my configuration?
Thank you for helping.

What is your config? Do you use DNSOverTLS?

I use whatever is the default in Fedora 42. I haven´t changed anything DNS-related aside from using dnsmasq for local name resolution.

The problem was not fedora updates but systemd-resolved.service when DoT is activated. I can't say why!
I needed to use dns servers configured with DoT, so I activated this service in systemd-resolved.service and firefox and thunderbird took 3 minutes to be launched.
I disabled systemd-resolved.service, and configured stubby to have the DoT service enabled and now thunderbird and firefox are correctly launched.

I don't know about Thunderbird, but Firefox has its own settings for DNS over HTTP. You could try adjusting them.
