Arch Linux

I can confirm that this is happening.
Not only in the print dialog (Control - P)
But also via the hamburger menu, Print.

I experienced the same issue after installing cups, however the issue also persists after uninstalling cups. libcups could not be uninstalled on my system as a dependency for several other packages.

With cups removed:
pacman -Q firefox libcups cups
firefox 113.0.2-1
libcups 1:2.4.3-1
error: package 'cups' was not found

Crash report: https://crash-stats.mozilla.org/report/index/a57089e0-aa1b-4ce7-b2c7-513ef0230605

With cups reinstalled:
pacman -Q firefox libcups cups
firefox 113.0.2-1
libcups 1:2.4.3-1
cups 1:2.4.3-1

Crash report: https://crash-stats.mozilla.org/report/index/4eaf94e9-72a7-47b8-b649-1c1610230605

Both cases crash appears to occur in cupsCopyDest.

I am also experiencing this issue when I try printing (CTRL P)

firefox 113.0.2-1
libcups 1:2.4.3-1
cups 1:2.4.3-1

I am experiencing this too. I also notice that lp is terminating with a segfault:

$ echo test | lp
fish: Process 30495, 'lp' from job 1, 'echo test | lp' terminated by signal SIGSEGV (Address boundary error)

$ pacman -Qo lp
/usr/bin/lp is owned by cups 1:2.4.3-1

Can confirm this is happening as well:

Finally some sanity...thanks @loqs! I cannot repro here (in a test VM or on a real system) so clearly it doesn't trigger for everyone.
