Filtering by tag does not work on Firefox

This happens:

* I open the filter menu with the three-lines icon bottom right.
* Select one tag, for example "Accessibility"
* Click on "Apply filters"
* The visualizations reloads, still unfiltered.
* Filtering by country works as expected.

In general, my prayer is to DEVELOP EVERYTHING FOR FIREFOX FIRST. Chrome is optimized for adtech delivery, and runs contrary to open culture.
