Bug#943504: firefox-esr: Firefox Wayland crashes at startup

[Andres Salomon]

FYI, I'm running firefox-esr 78.7.0esr-1 in wayland, and it does seem to 
be fixed. This bug can probably be closed.

It appears that the issue was fixed upstream, they now sanitize the name
before it's used in DBUS addresses:

Seems to be possible to fix that with the configuration option
--enable-default-toolkit=cairo-gtk3-wayland
like it is done on the newer official builds.
I don't know how this changes the build requirements.

Don't know if you want to do such a change in stable.

Maybe you just want to add a check for GDK_BACKEND.
Then you can add --no-remote in /usr/bin/firefox
That changes behaviour. But only in the case when it would crash.
So I think no one would complain about that.
Maybe besides displaying a proper warning.

Confirmed: Firefox 68.2.0esr-1~deb10u1 Wayland mode DBUS bug
Firefox does not start with MOZ_ENABLE_WAYLAND=1 (or old GDK_BACKEND=wayland)
Works with --no-remote, but once open can't open URLs from other applications.

MOZ_ENABLE_WAYLAND=1 firefox-esr --no-remote # temp. partial workaround

Related upstream bug to consider (along with Benoît Laniel's fix):

Package: firefox-esr
Version: 68.2.0esr-1~deb10u1
Severity: important
Tags: newcomer

Dear Maintainer,

When setting MOZ_ENABLE_WAYLAND=1, Firefox crashes at startup.

It seems the problem comes from DBUS: org.mozilla.firefox-esr is an 
invalid

interface name.
Debian package defines MOZ_APP_REMOTINGNAME as $(call 
uc_first,$($(PRODUCT)))

so it ends up being Firefox-esr for this package.

I fixed it using

export MOZ_APP_REMOTINGNAME := $(subst -,_,$(call 
uc_first,$($(PRODUCT


in debian/rules so the DBUS interface name is valid while being 
different from

firefox (non ESR).

Thank you.
