[SOLVED] Firefox spams journal and sometimes malfunctions

stea · 2023-09-22 19:01:06

My journal is spammed with lines like

Sep 17 00:01:36 geras firefox.desktop[1956]: [Parent 1956, Main Thread] WARNING: invalid (NULL) pointer instance: 'glib warning', file /build/firefox/src/firefox-117.0.1/toolkit/xre/nsSigHandlers.cpp:167

whenever I interact with Firefox. Specifically, it happens whenever I type on the search bar, hover my cursor over elements on the toolbar (e.g., the refresh button, back button, tabs, bookmarks, bookmark folders). It also happens when I hover over or click on links.

Aside from the journal being spammed, there are times when my keyboard input is delayed for a couple of seconds. When the characters I type finally show up, I'm spammed with

Sep 19 15:07:57 geras firefox.desktop[8794]: [Parent 8794, Main Thread] WARNING: Process Key Event failed: Timeout was reached.: 'glib warning', file /build/firefox/src/firefox-117.0.1/toolkit/xre/nsSigHandlers.cpp:167

Sep 19 15:07:57 geras firefox[8794]: Process Key Event failed: Timeout was reached.

I included a screencast of this at the bottom of the post. The delay doesn't go away on its own (although there is the possibility that I just haven't waited long enough), so I've been restarting Firefox to temporarily fix it.

I looked at the Troubleshooting section of Arch wiki's page on Firefox, but the problem still persists when Firefox is started in Troubleshoot Mode. I looked at nsSigHandlers.cpp, but I didn't really know what to do from there.

A full boot session http://0x0.st/HOdi.txt
The same boot session with "-p 3" http://0x0.st/HOdK.txt
The same boot session with some lines deleted http://0x0.st/HOdb.txt
I thought it might be helpful if there was a version where the spam was purged, so I used sed to delete lines containing "invalid (NULL) pointer instance" and "g_signal_emit_by_name: assertion". The number of lines went from 143469 to 7961.

Screencast of journal being spammed as I interact with Firefox with my keyboard and (invisible) cursor http://0x0.st/HOn3.webm
A screencast where I immediately begin typing, but the characters only show up 18 seconds later http://0x0.st/HOnY.webm

Edit: sorry, yes happens in -safe-mode (I should really read threads before answering

NS_DEBUG_WARNING sounds like this is supposed to be a debug output, is this the normal repo version, a nightly or some flatpak?

https://bugzilla.mozilla.org/show_bug.cgi?id=1802297
https://bugzilla.mozilla.org/show_bug.cgi?id=1798621

You could check "G_DEBUG=fatal-warnings" to see whether it's the same (still/again)
Or did you maybe export G_MESSAGES_DEBUG ?

This is the normal repo version.

I haven't exported G_MESSAGES_DEBUG, and setting G_DEBUG to fatal-warnings produced:

The more interesting piece will hopefully be the https://wiki.archlinux.org/title/Core_d … _core_dump

The backtrace is just somewhere deep in XUL, if FF is in the debug repos, https://wiki.archlinux.org/title/Debugg … ing_traces might shed more light on this.

Google has your error in relation to IMs, specifically ibus - do you use that/such?

Firefox wasn't in extra-debug, so I'm not sure what to do for libxul.so.
Yes, I use Mozc as an input method, installed from the AUR.

Yes, I use Mozc as an input method, installed from the AUR.

It would probably be a very good idea to try to disable that and see how FF responds.
It might also just need a recompilation.

stea · 2023-09-24 07:09:54

I disabled Mozc and get no IBus errors, although the other errors still persist. IBus errors actually never occur for me except for this one boot session, which I should've said earlier. I did a grep of my whole journal, just to double-check.
