Knowledgebas Link not opening in Firefox

Infos:

  • Used Zammad version: 6.3.1
  • Used Zammad installation type: Package on Ubuntu Server 24.04LTS
  • Client Operating system: Tested with Windows 10 Pro, Windows Server 2012 R2 and Windows Server 2019
  • Browser + version: Tested with Firefox 126.0.1 64bit and 115.11esr 32bit

Expected behavior:

When using firefox and clicking on knowlegdebase link, knowlegdebase opens in new tab, just as it does on Chrome and Edge.

Actual behavior:

When using Firefox, klicking on knowledgbase link opens new tab with blank page (about:blank). Hoever, if I manually enter https://mydomain/help/de-de, firefox is able to load the knowledgebase.

Steps to reproduce the behavior:

Open Firefox, navigate to Zamad ans login, klick on Knowledgebas Link in the menu on the left.

Has anyone had the same problem?

Dont’t know how, but now it works. Maybe just because I deactivated and re-activated the knowledgebase. Also the knowledgebase does not open in a seperate tab any more (in any browser), which is fine for me.
