Steps to reproduce the behaviour

NOTE:

1. Same Jabref extension works fine with JabRef 5.4 within the same corporate firewalled network environment and on the same Windows 10 computer.

2. The following bug report is being reported with a slightly earlier version of JabRef 5.10 due to long lead time involved in installing latest 5.10 build within corporate environment.

3. Download and admin install JabRef 5.10 within a corporate firewall environment on Windows 10 computer, post install details as follows.

@calixtus - Is this related to #10044?
@bhatiaa1 JabRef 5.4 is already a little old. To find the regression window, It would be really nice to know, if JabRef 5.9 works for you.
