firefox-nightly-bin wrapper needs to include libEGL on LD_LIBRARY_PATH

[colemickens]

I think that the firefox-nightly-bin wrapper firefox needs to have LD_LIBRARY_PATH further augmented to include libglvnd, for example, to provide the libEGL.

Note, it still doesn't work for me, but it seems like it's necessary at least.

I think this is a known problem with wayland did a quick search and i came up with this 2 links:

• https://bugzilla.mozilla.org/show_bug.cgi?id=1489902
• https://github.com/xhorak/firefox-devedition-flatpak/issues/90

I think if you disable webrender you would be fine.

I suggest you subscribe to those tickets, and follow progress there.

@garbas Yeah, things are fine with WebRender disabled, and even with libGDL on LD_LIBRARY_PATH, it doesn't seem to work due to the bug you linked on BugZilla.

I made this change in my nixpkgs PR adding a Chromium Wayland build, it should be an easy thing to add to the wrapper here. I will try my hand at it whenever the Firefox WebRender builds are generally usable w/ Wayland.

I have been told that wayland support can be enabled by setting the environment variable MOZ_ENABLE_WAYLAND which will default to either x11 or wayland based on the commit message which introduce it.

We should fix that in nixpkgs, and set it to 1 in the Firefox wrapper of Nixpkgs.

I think it's far too early to be doing that. As much as I want to live in a fully-Wayland world, Firefox still has too many issues to default to Wayland (crashes, performance, broken/missing features, etc).

OTOH, adding libEGL to firefox-nightly can be a benefit in case the user opts into Wayland, and also this will simply be needed for WebRender on NixOS as I understand it...
