Original GitHub issue: https://github.com/netblue30/firejail/issues/4411

Could it be possible that running Firejail could cause apps to show superuser in the titlebar?

Might be related to #258, but we won't be sure until you provide some more context. What's your OS, firejail version, window manager etcetera?

I figured it out. It is FJ, I disabled it, and no more superuser in titlebar.

Happy to read you've made some progress. Disabling Firejail is one way of dealing with the titlebar issue, but it's not something we'd advise. Firejail should be able to cope with that, but it's up to you to be the final judge. Personally I'd prefer a mangled titlebar and run the affected apps in a sandbox, be it firejail or something similar. If you have the time to debug this further, we can help and try to reproduce. But like already mentioned above we'd need detailed info. Just voicing my personal view on this situation, I do understand it can become tedious to debug and time is precious.

Regards

FWIW: Maybe ignore noroot stops those messages (at the price of a weaker sandbox).

No mangled titlebar...on the Debian forums they were trying to tell me I was running as root since alot of my apps says superuser in the titlebar. I ALWAYS forget about Firejail and it's usually the culprit with problems nobody can figure out.
