1699474 - Firefox on Ubuntu New Tab crashes

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect, P1)

Description

[Yohan]

Attachment: Window showing the error. I had to click 3 times on a link for it to open, the first 2 crashed

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:85.0) Gecko/20100101 Firefox/85.0

Steps to reproduce:

This is a new Bug opened as requested by :gcp on similar thread. This error has been happening for me for quite a while, and I will copy my reports here. What happens is simply, from time to time, when you middle click, or CTRL+click on a link to open on a new tab, that tab crashes completely. It does not open, the title is the link, most of keyboard shortcuts do not work (for example, CTRL+T or CTRL+W work, but CTRL+SHIFT+A does not), trying to use it on any way it does not work.

Retrying the link will work at some point. Might need 3, 4, 8 tries, or even just one.

A couple of info that could help:

• This is a work computer where I do not have sudo;
• My hard drive is encrypted;
• Although the problem is intermittent, it will happen in every Firefox session;
• Sometimes, I want to complete restart Firefox, but even closing some windows, if I go to "System Active" (KDE task manager) there will still be a xhroot and a Firefox process showing even with all windows closed. I need to kill those.

Link for previous data/report

• This link has the list of of shortcuts that work or don't when a tab crashes https://bugzilla.mozilla.org/show_bug.cgi?id=1604218#c5 ;
• This is my previous report, with the data on my previous system https://bugzilla.mozilla.org/show_bug.cgi?id=1604218#c31 ;
• Disabling add-ons does not stop it from happening ;
• My home page is the default one.

About the last point, if I open a new window (CTRL+N) and the start tab is the one broke, if you simply click on a link to open on that TAB, it will show the loading icon but nothing will happen.

Attachment: Example of hang process after closing firefox

The attached image shows the processes that are on the system, when searching for firefox, AFTER closing all windows. There is always a Sandbox -> Chroot hang when at least one tab crashed

Attachment: Result of restarting firefox without closing the hang process

Continuing on the examples after the previous screenshot, this is what happens if I try to open firefox again without closing the hang sandbox -> chroot processes. No matter how many tabs or windows I open, none will work.

If I close all windows, after a while (30 sec+, not sure exactly how long) the processes will be finished and if I reopen firefox it comes back to life.

Hey Yohan,
I tried reproducing this issue on the latest versions of Firefox Nightly 88.0a1 (2021-03-19), beta 87.0 and release 86.0.1 on Ununtu 20.04 but it doesn't crash for me.

Can you test the issue while in Safe Mode? You can find helpful info here : https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode .
Also a fresh new profile could help. You can find more about creating a new profile here : https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile .
If possible, you can test this issue on the nightly build as well. Download the build from : https://www.mozilla.org/en-US/firefox/nightly/all/ .

Hey Andrei,

I posted screenshots of the issues both on a new profile and on safe mode on my main profile. I asked the support team to install at least 86.0.1, as soon as they do it I will processed with the tests.

Setting a component for this issue in order to get the dev team involved.
If you feel it's an incorrect one please feel free to change it to a more appropriate one.

Delete your current Firefox configuration directory. Run the following in the terminal: rm -r ~/.mozilla/firefox/
Start Firefox browser. A new . mozilla/firefox/ directory will be automatically created with fresh configuration files in it.
Try Firefox now and see if it works again.
