firefox 64.0.2 error in tc10

[udo]

Nobody else seems to experience these gtk3 file dialog crashes.

Nevertheless, here is what I found in the meantime:

• upon a fresh start/reboot `gsettings list-schemas` returns a list of schemas (as expected)
• after loading firefox and dependencies, the same command returns "no schemas installed"
• `ls -l /usr/local/share/glib-2.0/schemas/gschemas.compiled` reveals that permissions on this file have changed
• `sudo chmod 644 /usr/local/share/glib-2.0/schemas/gschemas.compiled` then resolves the issue

Thus, I was able to resolve the issue now - though not in a very elegant way.

Cheers, udo.
