Firefox lags and sometimes freezes completely on Devuan 6

I haven't done anything wrong. Just XFCE install, i5 1235U laptop, but firefox freezes sometimes. It's weird but doesn't happen on Gnome Wayland.

Maybe doesn't help you, but I have no problems using Firefox on XFCE on my I3 or i5 computers, using Devuan from 'server' media installs.....

Do you happen to have any extensions installed. Also you my try running Firefox from terminal, like this:

firefox > out.txt 2>&1

Firefox outputs quite a lot. When it freezes, wait a bit. The output might be buffered, so give it a minute. You might examine out.txt while firefox is still running and also after you stop it.

Re: Firefox lags and sometimes freezes completely on Devuan 6

Peace and Good to all!
My Firefox are freezing too. but only in multi function.
First notice when i open Firefox and Libre Office togheter (so exclude GTK from Libre office corrects the problem eith some modifications in Firefox)
In Firefox go to configuration>Performance (Desempenho in portuguese) > deactivated option
And deactivet so: Use hardware acceleration
And in browser type:
about:config
Skip risk screen and type
gfx.webrender.software
change the first option to true
after that type:
layers.acceleration.disabled
change to true
and that:
webgl.disabled
change to true

So i can use Firefox with Libre Office, but not Firefox with OBS-studio and so
In Firedox browser again, type:
about:config
Skip risk screen and type
gfx.webrender.all
alterar gfx.webrender.all to true
gfx.x11-egl.force-disabled
change to true
media.ffmpeg.vaapi.enabled  (original in boolean)
change to false
and so
gfx.webrender.compositor
change to false

So i can use OBS-Studio with Firefox;

But is freezing again with Thunderbird at same time:
im trying right now (haha - kkk -  jaja ) and like Terminator:  "i wil be back"

dom.ipc.processCount.webIsolated (original in mine is 4)
change to 2 or4

So im a Gigabyte Aorus B450m Elite, AMD Ryzen 7 3700x, 16 GB RAM, Asus/Nvidia GTC 1050 Ti, SSD Samsumg  970 EVO Plus , Devuan-GNU, XFCE sysVinit, Linux 6.12.90+deb13.1-amd64 (with a Barracuda HD with Windows11)

Re: Firefox lags and sometimes freezes completely on Devuan 6

Peace and Good Again (now with a solution for the use of Firefox and Thunderbird toguether)
first of all
purple.disable_foreground_integration
Change to true

toolkit.cosmeticAnimations.enabled
change to false

mail.spotlight.enable
change to false

browser.tabs.unloadOnLowMemory
change to false

dom.ipc.processCount
change to 1 or 2

accessibility.force_disabled
change to 1

widget.use-dbus-menu
change to false

browser.tabs.remote.autostart
change to true

widget.use-dbus-menu
change to false

Change the ahead lines in Thunderbird (configuration -engine icon, then scroll down at config editor, advanced preferences) too, and also change that lines:
gfx.webrender.software
change to true

layers.acceleration.disabled
change to true

webgl.disabled
change to true

gfx.x11-egl.force-disabled
change to true

widget.gtk.cursor-async.enabled
change to false

so trhe lines doenst do the work alone, at least for me. Indeed in this case i need to change some lines to configure the rendering method.

nano /usr/share/applications/firefox-esr.desktop
Exec=env -i DISPLAY=:0 dbus-run-session /usr/lib/firefox-esr/firefox-esr %u

nano /usr/share/applications/thunderbird.desktop
Exec=env -i DISPLAY=:0 dbus-run-session /usr/bin/thunderbird %u

And now i m  thinking if changing only the archive /usr/share/applications/firefox-esr.desktop i can get stop the freezes??? Anyone can test, and report? (im thinking in test too hhehehe).

Re: Firefox lags and sometimes freezes completely on Devuan 6

That's a lot of workarounds. It could be graphics stack / acceleration related. In such cases I would normally install a newer kernel from backports and see if that resolves it.

Also you will need the "non-free" drm firmware installed for Intel or AMD GPUs - that's the first step.

install the uBlock Origin extension. Most of the ads on the 'modern' internet make it completely unusable.

Re: Firefox lags and sometimes freezes completely on Devuan 6

remember also a time when had microstuttering , probablz with ryzen 2600 or 3600, *could also have been birstol ridge
but not how it got solved

would try to set bios at default position and disable bar,
see if this makes a change, and update bios.

good luck.

Re: Firefox lags and sometimes freezes completely on Devuan 6

For me it was the following problem:
Do you have an AMD graphics card?
What does the command "sudo dmesg -l err"?
You may find a line with the following error message:
"ring gfx-0.0.0 timeout, but soft recovered".
It should be a problem with the AMD graphics driver and you can fix it simply by disabling the composite effects of XFCE!
It is due to the interaction of the XFCE compositor and the AMD graphics driver.
Other desktops do not have this problem or extremely rare!
(I use Cinnamon for exactly this reason, although I like XFCE)
You could also use picom as a compositor!
But there are other problems: "https://bbs.archlinux.org/viewtopic.php?id-306908"

Re: Firefox lags and sometimes freezes completely on Devuan 6

That's more of a workaround. That error is amdgpu driver related. So the first step should be to compile a newer kernel to see if this has been fixed. There are usually newer kernels in backports, so if you don't want to compile your own, install the latest, reboot and test.
