2011120 - Firefox 147.0 crashing frequently.

Status: RESOLVED DUPLICATE of bug 1999029

(Core :: Widget: Gtk, defect, P3)

Description

[Bill Mattison]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:147.0) Gecko/20100101 Firefox/147.0

Steps to reproduce:

(Fedora 42 Workstation; Gnome 48; Wayland; all last updated Thursday morning, January 15, 2026)

Firefox has crashed numerous times in the past at least 3 days, all since updating to 147.0 on January 15, 2026.

• twice during a jitsi meeting Friday night.
• at least once while connecting or connected to the CIRA Slider web site.
• several times tonight while viewing videos in youtube, some while logged in, some while not logged in.
  All crashes were sudden, no symptoms before the crash.

Actual results:

In all cases, it just crashed and a little window about submitting a crash report popped up.

Expected results:

The jitsi meeting should have just continued.

The youtube videos should have just played to completion.

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

The crashes look a lot like bug 1990430, but on a newer Firefox version than the landed patch there. Any idea?

IMHO dupe of Bug 1999029.
