It appears to be sandbox/seccomp related so perhaps glibc just like
chrome? Workaround:

- install ublock
- modify "security.sandbox.content.level" from "4" to "2"
- restart firefox and bring back "security.sandbox.content.level" to "4"
- restart firefox and enjoy ublock

No idea what's wrong exactly though.
