Details

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:122.0) Gecko/20100101 Firefox/122.0

Steps to reproduce:

  • With no active Firefox window, clickon a link on a Thunderbird message.

Actual results:

Firefox window opens, but the requested web page does not appear. If I type an URL and hit enter, the URL disappears, and the Firefox page remains on the home page.

Expected results:

I expect the target of the link on the Thunderbird message to appear. Additional information:

  • If I first initiate Firefox (from command line or desktop/panel icon, not from Thunderbird), then clicking on a link within a Thunderbird message works as I expect it to: the requested web page is displayed.

  • Firefox is my default browser.

  • The errors shown (which appears many times) are:
    [Parent 1982501, IPC Launch] WARNING: fork() failed: Operation not permitted: file /build/firefox-BRnaoF/firefox-122.0+build1/ipc/chromium/src/base/process_util_linux.cc:308
    [Parent 1982501, IPC I/O Parent] WARNING: Failed to launch socket subprocess: file /build/firefox-BRnaoF/firefox-122.0+build1/ipc/glue/GeckoChildProcessHost.cpp:787

  • Thunderbird version 115.6.1, FIrefox version 122, on Ubuntu 22.04.3.

  • Don't know if it matters, but Sandbox settings are all true or zero, except for Win32k Lockdown (disabled because not relevant to Linux).

It appears to be a permission error on the fork statement. Apparmor and SELinux are not active. Starting Thunderbird in safe mode does not help.

It is possible it is due to my environment, but don't know where to look, debug, or what to change.

I'll try to reproduce this following the steps!

I cannot reproduce the issue 115.6.1 (64-bit) and 122.0 (64-bit) under Fedora. Could you explore also the askubuntu.com community, they might be able to help. Please reopen if you think it should be investigated further here.

(I'm the OP - I reported the bug. The bug was already closed, but wanted to document this in case anyone else comes across this issue.)

Seems to work with Thunderbird 115.7.0 and Firefox 122.0.1. Don't think I made any other changes to the system, other than the regular updates.

Spoke too soon. With the updated Firefox 123, the bug has returned.
