My default browser is Firefox version 121.0.



Like I wrote, I've been using MS Word since version 1. Office 95, XP, and 2000 without this problem. And I cannot see any difference between the links that fail and the link that works.


I have a couple more ideas to try out...
I copied the good link to another location in my document and when I click it, it works.
Then I replaced the link contents with the contents of the bad link and it didn't work.


But if I copy the link into a new LibreOffice "Word" document, then the link works correctly.
