1744882 - After update to version 95 on Ubuntu 14.04 LTS, firefox freezes when I close any window (SW WR/Unity X11)

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

Attachment: GeckMain.png

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Safari/537.36

Steps to reproduce:

I was running version 94.02 and upgraded to version 95, after that it started to freeze every time I try to close a window or the firefox itself.
I fresh install of firefox 95 had the same result.
I'm running on Ubuntu Linux 14.04 LTS

Actual results:

After closing any window, for example the help window or the firefox itself the all windows become unresponsive and the GekoMain process starts running in loop consuming 100% of cpu, the only way out is to kill the process.
It seems to be happening only with pop-up windows or the main window itself, for example, if I click on the help menu and try to close the help window it freezes, or when I try to login into a site using my google credentials, it opens a pop-up for me to select the account and when it try to close it freezes.
Closing tabs seems ok, so far.
The problem happened on two different Ubuntu 14.04 machines, in 16.04 it worked.

Expected results:

To be able to just close the window.

Can you please use mozregression tool to find the broken commit?

I'm having a hard time installing mozregression_tool, but meanwhile I tested some beta versions and found out that
it broke on 95.0b3 - build (20211104185958). On 95.0b2 and below it works.
I hope it helps.

I give it another try on the mozregression tool.

(In reply to alberto.pires.on from comment #15)
Does this crash/hang still occur with latest Nightly?
(bug 1750017 has been fixed)

Comment 17

[alberto.pires.on]

Yes, I've just tested on firefox-98.0a1.en-US.linux-x86_64 and it still hangs, then I need to kill it.

Comment 18

[Martin Stránský [:stransky] (ni? me)]

Hm, I can't build Firefox there and also I'm unable to install gtk3 debug symbols so I'm unable to do anything there.

Comment 19

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

The bug has a crash signature, thus the bug will be considered confirmed.

Comment 20

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

Closing because no crashes reported for 12 weeks.
