Original GitHub issue: https://github.com/netblue30/firejail/issues/1937

I'm having problems with FF 60 on Fedora 28 KDE with the existing profile. Whenever I close Firefox I can still see processes in the task manager (and FF can't be restarted):

After killing those processes and starting FF anew, quite often it's not possible to load any websites.

I haven't had time enough to do a thorough research regarding the culprit - but a combination of 3 measures seem to be necessary here to make FF work reliably again:

Remove ptrace from seccomp.drop
Comment nodbus
Comment private-dev

Can anybody reproduce my findings?

Oops - I just saw this pull request. And indeed - the culprit seems to be tracelog. After commenting it and reverting the other changes everything seems to work well again.
