Tried signing out of google account several times, I still see things about Jenner, Kardashian, and Musk.

On my computer I need always to press "F5" before the filtering gets active. So I need to load the page twice. I also can't find the "show / hide hidden toppics" button anywhere. This addon is a very good idea, but needs some improvement/debugging.

Update 04-Aug-22: No more need to press "F5" (you fixed it well!), but Google decided not to show all topics instantly, but loads more topics when you scroll down. Those new loaded topics are not filtered. Too bad. Therefore I still get annoyed by sports, Kardashians, Trump etc...
