bug#38565: Cannot run pre-compiled Firefox

[Arne Babenhauserheide]

Hi,


Until about two months ago I could run firefox binaries downloaded via
https://download.mozilla.org/?product=firefox-latest-ssl&os=linux64&lang=en-US

For about two months now I’m seeing segfaults when I try to run it.

Previously I got it working with the following setup:

cd $HOME/Downloads/firefox
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:/run/current-system/profile/lib/:$HOME/.guix-profile/lib/:$HOME/.guix-profile/lib/nss/:$HOME/.guix-profile/lib/lib/:/gnu/store/69x60a1pn0mf5jv68al8awjfkyp1miwi-gcc-8.3.0-lib/lib/:./browser:."
./firefox-bin

This used to work with only minor limitations.


Now what I get is

./firefox-bin
Speicherzugriffsfehler (segmentation fault)


With gdb I get the following:

$ gdb ./firefox-bin
…
Reading symbols from ./firefox-bin...
(No debugging symbols found in ./firefox-bin)
(gdb) run
Starting program: /home/arne/Downloads/firefox/firefox-bin

Program received signal SIGSEGV, Segmentation fault.
0x0000000000000000 in ?? ()
(gdb) bt
#0  0x0000000000000000 in ?? ()
#1  0x00007ffff7c28d38 in ?? ()
#2  0x0000000000000000 in ?? ()


Do you know a way to fix this? I need a way to test different firefox
versions, because I use Guix in homeoffice which includes web
development. If I can’t get these to run, I might have to switch away to
a different distribution. There’s so much going for Guix that I want to
keep it, but being able to run binaries compiled for Linux X86_64 is a
hard requirement for work.


Best wishes,
Arne

LD_LIBRARY_PATH forces firefox-bin to use libraries from the given
directories.  These might not be ABI compatible, so a segfault is one of
the expected outcomes.

I’m surprised it worked before, because often it doesn’t.  Do you happen
to know what libraries and their exact versions this firefox binary
expects?

Yes — I’m looking for a way to get it working again.

If it worked until about 2 months ago it might be related to the glibc
bump. One thing you could do is create a profile from before the
core-updates merge and LD_PRELOAD from there.

Not an immediate solution, but it would be nice if they provided a
flatpack image.

How can I do that? Can I simply specify the commit to use?

Looks like this already exists:

Thank you!

I now have a working setup:

# sudo flatpak install --from https://firefox-flatpak.mojefedora.cz/org.mozilla.FirefoxDevEdition.flatpakref
# sudo flatpak install flathub org.freedesktop.Platform.ffmpeg

flatpak run org.mozilla.FirefoxDevEdition

Thank you!

FWIW, this is an upstream flatpak bug.  See the discussions here:

https://issues.guix.gnu.org/35591
https://github.com/flatpak/flatpak/issues/3612

I’m closing this issue because you have confirmed that using Firefox
with Flatpak works fine for you.
