1828347 - Firefox randomly crashes the system when playing Youtube shorts

Status: RESOLVED INCOMPLETE

(Core :: Audio/Video: Playback, defect)

Description

[juanjosealca]

Attachment: prevboot.txt

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:109.0) Gecko/20100101 Firefox/112.0

Steps to reproduce:

Open Firefox (snap). Start playing Youtube shorts.

My system:
Ubuntu 22.04.2. Linux 5.19.0-38-generic
Gnome: 42.5
CPU Ryzen 7 7700X.
RAM 32 GB 6000 30L
GPU: NVIDIA RTX 2060 Super (Driver 525.105.17)

Actual results:

Firefox freezes the system (it's not possible to get a TTY, restart it's the only option. The bug in Firefox freezes gnome-shell too) after playing Youtube shorts / videos.

In the log Firefox produces the following warnings:

I've attached the journalctl log of the session before the crash

Expected results:

Firefox should normally decode the videos, without freezing / crashing the system.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

[C.M.Chang[:chunmin]]

From the log, tt seems Fx failed to parse the mp4 metadata, but this shouldn't cause a crash.

Hey juanjosealca, thanks for the report! Unfortunately, I cannot reproduce this on my end. Can you provide the link of the youtube short that cause a crash and the crash report? The crash report can be found in about:crashes page. Can you submit the crash report and paste the link to here?
