Please describe in detail what you did and what happened. Note; Some of the links are PDF files.

Open this URL: https://www.moods.club/en/ This is the monthly program of the club for October. I click on any program item/date and nothing (an empty line is added at the bottom of the segement) happens. In other browsers the detail-page for that concert opens. The only way to get at this information in FF is right-clicking on the item and using "Open link in New Tab".

I had no problem with the website. Make sure you are not blocking content.
