No keyboard input in Firefox window; logging out and logging back in fixes it

ladlelord · April 4, 2025, 11:55pm

My laptop’s keyboard input doesn’t work in Firefox. I can interact with Firefox using the trackpad, but not the keyboard. Keyboard input works in other applications. When I log out and log back in, keyboard input into Firefox appears to work. For what it’s worth, I noticed this recently in Fedora 41, but I’m using Fedora 42 Beta now.

How can I troubleshoot this further?

Is this Firefox from RPM or Flatpak?

If flatpak then try with the RPM version.

ladlelord · April 6, 2025, 4:15am

RPM version.

Once the problem occurs check both the system and user journals for error logs.

I also have the same problem. Slack electron app doesn’t “release” the keyboard, closing it allows Firefox to regain the keyboard control

Timeline:

00:10 - Firefox launched after boot and log in; keyboard input doesn’t work in Firefox
00:20 - Log out, log back in, and launch Firefox; keyboard input in Firefox works.

These two lines show up at 00:10 but not 00:20, so it looks like Firefox is having trouble connecting to ibus?

Are you running other apps that might be causing the problem as jsnjack found?

The error message shows: WARNING: Unable to connect to ibus: Could not connect: Connection refused: 'glib warning', This message is associated with attempts to run GUI apps using sudo (maybe without the -H option or corresponding sudo configuration). How are you launching Firefox? Do you have multiple Firefox windows? What Firefox extensions are you using (see about:support page). Here:

I’m launching Firefox normally through the GUI: I boot the machine, log in, type “firefox” in the Gnome app search and hit Enter. I notice no keyboard input, so I log out, log back in, and launch Firefox the exact same way, and keyboard input works.

I have Firefox set to open previous session tab and windows, so Firefox usually starts with multiple tabs and windows open.

Firefox extensions:

System theme — auto	theme	1.4.1	false	default-theme@mozilla.org

I took a stab and uninstalled the GNOME Shell integration add-on/extension, and this behavior seems to have changed? After a reboot, the first launch of Firefox exhibited this “no keyboard input” behavior, but after closing and re-opening Firefox, keyboard input worked, which was different behavior since previously I had to to log out and log back in before keyboard input started working again.

I rebooted again, and keyboard input worked on Firefox’s first launch.

I rebooted a third time, and the original behavior returned where I had to log out and log back in before Firefox didn’t throw an ibus warning in the logs. When Firefox was throwing the ibus warning, I tried launching Firefox using the Troubleshoot Mode by clicking Help → Troubleshoot Mode, which disables all the add-ons and extensions and reboots Firefox in a “safe mode” of sorts, but that didn’t solve the problem either. So, I don’t think it’s any of my add-ons or extensions? Very strange.

ladlelord · April 8, 2025, 3:49am

I don’t believe so. I launched Firefox immediately after logging into Gnome.

gnwiii · April 8, 2025, 12:48pm

Does the issue occur if you revert this setting? I worry that this is hard to implement correctly for web sites that connect to an unstable list of 3rd party sites (I tend to only grant temporary access in NoScript). You could check to see if the issue is associated with a particular site by only having one site open when ending in a session.

Next steps:

consider Gnome Shell’s Focus Stealing Prevention (FSP). I wonder if there is some clash between preserving previous sessions in Firefox and FSP.
check permissions (ls -lRZ ~/.mozilla/firefox). I see files/directories owned by me with 'unconfined_u:object_r:mozilla_home_t:s0`.
check for the issue with a newly created user (default Firefox configuration). Maybe try with default settings and then add the “open previous session” setting.
