Thanks for reply, Daniel!
I have done some more testing and this problem seems to be specific to latest Firefox (24.0, running on Windows 8). FF is in Polish language version (Windows 8 has US locale). That is, when I log into Jenkins using Chrome, the project name stays as it should be.
My colleagues are running FF on various Linux distros and they have the same problem, so it seems FF-specific and perhaps it is created by server locale as well:
The server is Ubuntu Server 12.04, Polish locale set:
LANG=pl_PL.UTF-8
LANGUAGE=
LC_CTYPE="pl_PL.UTF-8"
LC_NUMERIC="pl_PL.UTF-8"
LC_TIME="pl_PL.UTF-8"
LC_COLLATE="pl_PL.UTF-8"
LC_MONETARY="pl_PL.UTF-8"
LC_MESSAGES="pl_PL.UTF-8"
LC_PAPER="pl_PL.UTF-8"
LC_NAME="pl_PL.UTF-8"
LC_ADDRESS="pl_PL.UTF-8"
LC_TELEPHONE="pl_PL.UTF-8"
LC_MEASUREMENT="pl_PL.UTF-8"
LC_IDENTIFICATION="pl_PL.UTF-8"
LC_ALL=
What's really strange is that some parts of the interface are localized and some parts are not localized:

If you need any testing, tweaking or changes, let me know, I'll help out.
This states resolved but we are on version 1.514 and are still seeing the Job Name being shown in the tabs on the main screen and not the Job Display Name.
