Since upgrading to firefox 73.0, visiting Netflix results in the yellow top bar with text "The plugin has crashed"

Additional info:
* Firefox 73.0

Steps to reproduce:
log in to netflix (or visit

I have already tried:
- Disabling all extensions / other plugins
- remove .mozilla directory and start from scratch
- launch firefox with environment variable MOZ_DISABLE_GMP_SANDBOX=1 (this one fixes the plugin crash, but sacrifices security)
This task depends upon

According to the forum threads, there may have been two related changes, one of which is the new syscalls which need to be whitelisted, the other of which is and fixed by two commits which are already in the glibc release tag.

Does our glibc package actually need changes for this, or is it all in whitelisting syscalls in firefox? I think it is the latter.

I don't know what are you waiting for? A patch is available from 24h. For the release of version 73.0.1.
You put them in trouble, you have to get to work.

How is it even possible that nobody in Mozilla tests such things, although it is known for two months that the changes made to glibc will cause problems with sandbox.

There is no firefox 73.0.1 release available upstream, so I have no clue what you are talking about and we obviously cannot upgrade to it.

What patch is "available from 24h"? It has not been linked here on this ticket, if you want to be useful you can actually specify what you are talking about and we can maybe make some progress.

If you're just here to act insulting, please don't. Nobody here is deliberately waiting to delay fixes for stuff. Sometimes people don't have time to take care of things within minutes of the things they don't know about, though.

I just don't consider this pressing enough to rush out a release with the patch from; I can patch 73.0.1 if Mozilla doesn't uplift it in time.

Fortunately, Firefox releases are regular.
It will not be the same as with GNU make that users will have to wait three years to correct a significant error (there were also lucky users of other distributions who were saved from the delay).
The conclusion of reporting software bugs in Archlinux does not make much sense, except for the informational dimension (users do not expect this).

Users wait for self-repair!!!

As a reminder, it is not Mozilla updated glibc in Archlinux (it should still be waiting in testing).

If anyone needs a build of Firefox with this bug fixed, here:
It's identical to the one from Arch Repositories with the exception of having this patch applied:
With this build, Netflix works for me just fine.

@god geu There is a simple work around to fix that problem while waiting for an new firefox release!
Downgrade these packages:
glibc 2.31-1 -> 2.30-3
lib32-glibc 2.31-1 -> 2.30-3

and it works again. :-)

Risky, but works for me too:

sudo pacman -U /var/cache/pacman/pkg/glibc-2.30-3-x86_64.pkg.tar.xz /var/cache/pacman/pkg/lib32-glibc-2.30-3-x86_64.pkg.tar.xz

Thanks :-)

Firefox 73.0.1 seems to have just hit the repos and it fixed it for me.
