firefox will not start after it crashed unexpectedly

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1917191

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

I can't send as it needs browser.

Can you open a terminal, type "firefox --safe-mode" followed by Enter, and let us know whether the application starts? If not, what is displayed in the terminal window?

This sounds similar to bug #1917147.

 I tried that already. It does not start and very little in the way of
feedback.

"Jesus said to him, 'I am the Way, and the Truth, and the Life; no one
comes to the Father but through Me'" (John 14:6).

If you don't mind installing debug packages that use a substantial amount of space, could you do the following:

    sudo apt install firefox-dbg
    firefox -g

At the (gdb) prompt, type "r" then return. When the crash happens, you should be getting another (gdb) prompt, type "t a a bt" then return, press the return key until there is no more of the backtrace to display, then copy-paste the contents of the terminal to a text file and attach it here.

This would be very helpful to understand where the crash is occuring.
Many thanks in advance!

Note: once you've done all the above, you can remove the debug packages to reclaim disk space with the following command:

    sudo apt remove firefox-dbg

Oliver,
I did what you said and sent the terminal output. Hope it helps you fix
the bug!

Thanks John, that's very useful indeed. The backtrace points to a known upstream bug (https://bugzilla.mozilla.org/show_bug.cgi?id=1694670), which is fixed in the upcoming firefox
87.0 (currently beta).
I'll consider cherry-picking the upstream patch for an Ubuntu update.

Is there a bug fix out there?

The beta builds (for the upcoming 87.0 release) contain the fix, if you're comfortable with adding a PPA and installing a beta version, you could try that (your confirmation that the bug is indeed fixed would be very valuable). The PPA is https://launchpad.net/~mozillateam/+archive/ubuntu/firefox-next/, and I'd recommend disabling it after you get a chance to test and confirm, because it's not recommended for normal use.

Thanks for the update.

A comment on the upstream bug says the fix was approved for 86.0.1, as soon as this is out the update will be reflected in Ubuntu.

Should I uninstall then reinstall firefox? It's not in updates.
