Comment:
I think this is an upstream bug, firejail doesn't seem to clear the title when it exits. You can try running these two commands:
```
printf "\033]0;title\007"
printf "\033]0;\a"
```
The first one sets the title, the second one, which firejail doesn't use, resets it to default. Please open an issue upstream @free-tinker.
