Hi Stefan and Konstantin,

The URL (reachable only within PSI) is http://lem03.psi.ch:8081/?cmd=custom&page=Mudas
Firefox is version 91.12.0esr (64-bit), but I had similar issues with chrome/chromium too.
The hangs seem to happen randomly so I have not been able to reproduce it yet. 
I have histories here  http://lem03.psi.ch:8081/?cmd=custom&page=Mudas&tab=3 (30 minutes each), but I have also histories popping up in modals though they do not cause any issues. 
I'll try to reproduce it in the coming few days and report again.

thanks,
Zaher
