[SOLVED] Tabs crash on Firefox 65

Hi, I just ran a packages update which included new Firefox version (65). Now when I try to load any page, the tab crashes. dmesg shows messages that look related:

[   97.855024] Web Content[2018]: segfault at 3e5e50000 ip 00007fec7679ddc0 sp 00007fff410dc2d0 error 4 in libX11.so.6.3.0[7fec76797000+88000]

This happens with Gnome on Wayland but not with Gnome on Xorg.

65 wayland isn't supposed to be the most stable thing ever (sadly). If you want to use FF_WL you are probably better off using nightly.

Re: [SOLVED] Tabs crash on Firefox 65

Running Firefox with GDK_BACKEND set to wayland (as mentioned here) seems to fix the issue:

$ GDK_BACKEND=wayland firefox

Issue has disappeared with recent system updates.
