Firefox fails to properly call the org.freedesktop.PowerManagement D-Bus interface. The issue was originally posted on Xfce's bug-tracker:

I've been doing some debugging and found that Firefox isn't calling the D-Bus interface method at org.freedesktop.PowerManagement.Inhibit -> Inhibit.

I used this command to monitor the calls and didn't see anything while I was playing media in Firefox: busctl --user monitor org.freedesktop.PowerManagement

The interesting thing is that it does call org.freedesktop.PowerManagement.Inhibit -> UnInhibit with the wrong cookie value every-time I pause the video, but it won't call Inhibit after I resume playback:

$ busctl --user monitor org.freedesktop.PowerManagement

  };

I also found that this issue is not easily reproducible. I restarted Firefox to test it again and it worked perfectly and called both functions normally with the correct values!

I normally keep Firefox open 24/7, so at some point it glitches out and stops calling Inhibit and keeps calling UnInhibit with a cached cookie value every time the playback is paused.

So this is almost certainly a regression in Firefox itself, will do some more digging and get back with the results here.

This is on a X11 desktop running Firefox v119, but the issue might have been present in older versions as well. The most recent change which touches the part of this D-Bus code is bug 1848084 (credit to bbhtt from Libera IRC for finding this).

I will continue to narrow down the steps required to reproduce this bug, if anyone has any clues please let me know. I use Firefox with several windows (including private windows) with at-least one window being always open at a time.

Can you run with MOZ_LOG="LinuxWakeLock:5" env variable? You'll get wake lock log from Firefox perspective and it's see what's called.

Ever confirmed: true
  • Update WAKE_LOCK_LOG to print 'this' which allows to sort operations by lock type
  • GetOrInsertNew() call always creates a new WakeLockTopic object so in this patch call it only if we create a new object.
  • Split mWaitingForDBusReply to mWaitingForDBusInhibit/mWaitingForDBusUninhibit. It allows to ignore repeated requests and also cancel
    opposite requests.
  • Use g_cancellable to cancel pending DBus operation if we want different wake lock action.

Depends on D192621

The steps to reproduce have changed a bit:

  1. Open Firefox
  2. Open a private window and load a video
  3. Close the window abruptly (without pausing/stopping the video, while it's still playing)
  4. Repeat step 2
  5. Confirm that power inhibition is broken

firefox_no_inhibit

I am using i3wm 4.23, no desktop environment.

Can confirm, this bug is still happening.

Archlinux up-to-date. XFCE.

Around 6 months ago, I was experiencing similar issues when Firefox would randomly stop inhibiting screensaver after some time, closing/opening tabs or just starting/stopping playback in more than two tabs (concurrently or sequentially).

Recently, with versions ~120 screensaver/lock inhibition stopped working completely.

I tested on Ubuntu-Mate 22.04, 23.10, 24.04 and vanilla Ubuntu 24.04 and the problem persists.
Firefox packages from Mozilla, Canonical PPA and Snap are all broken.

Here is the log of setting the lock to 1 minute, starting playback, waiting till screensaver actiavtes, cancel the the screensaver and stop playback:

Recently, with versions ~120 screensaver/lock inhibition stopped working completely.

It works for me on vanilla Ubuntu 23.10.

The video-playing inhibitor is only set when the video is visible (ie window is not minimized or fully covered by another window). Wayland is able to detect covered windows unlike X11 and was recently enabled in version 121. You can disable Wayland to see the difference:

 MOZ_ENABLE_WAYLAND=0 MOZ_LOG="LinuxWakeLock:5" firefox

I have the same issue on latest Gentoo, with Firefox 123.0

I have not tried Vanilla 23.10 and since other browsers do not have this issue I see no reason to blame/exclude any specific distro. Numerous reports support.
Now when I think about it, I tested both X and Wayland variants of Ubuntu so we can't blame X or Wayland either.
Maybe your routine/setup/hardware somehow avoids the issue and we should figure out how your setup is different from let's say generic install of "Vanilla" system in Virtualbox.

Also, why would you assume anyone taking their time to report the issue here, would test with the video in background or partially covered? It's a possibility, but common we are mostly gown-ups here.

Update.
Seems like the issue is not affecting KDE Plasma sessions.
I installed Plasma session on the same machine (Ubuntu Mate 23.10) and it works with the same Firefox instance without an issue.
Maybe "Media Playback" detection (indicated by the relevant Tray Icon) helps or maybe Plasma handling DBUS msgs differently.

I also tried freshly installed Kubuntu 24.04 and OpenSuSe Thumbleweed with plasma and they both work.

Who knows. There's too many bugs and few developers who works on them. Feel free to join and try to solve it. There's a mini-howto:
https://mastransky.wordpress.com/2023/07/04/no-one-fights-alone-a-guide-to-your-first-firefox-patch-on-linux/

Manu, please run Firefox on terminal and attach a log with MOZ_LOG="LinuxWakeLock:5" env variable so we can check why Wake lock is not applied.
Run as:

MOZ_LOG="LinuxWakeLock:5" firefox > log.txt 2>&1

and attach the log here.

Before closing firefox in the log I attached above, video was playing and there was NO inhibitor in dbus:

Thanks.

Been testing Nightly for the last 2 days, and the problem seems to be gone.
I'll continue to test for a few more days.

1 day later, happened again. Three big is still present in nightly.

When it happens in latest Nightly, try opening the video in a new window and see if playing creates a new inhibitor (as per Comment 42).

Please attach fresh MOZ_LOG="LinuxWakeLock:5" log from latest nightly.
Thanks.

I'm not sure if I'm having the same issue but Firefox doesn't prevent screensaver from activating on my system. I can reproduce this on both ESR and the latest Nightly.

I'm not sure if I'm having the same issue but Firefox doesn't prevent screensaver from activating on my system. I can reproduce this on both ESR and the latest Nightly.

This looks like a problem with your system setup or so. From the log:

So we got inhibit ID 16 and used it for uninhibit but it failed. Doesn't look like a Firefox bug.
