Doesn't work in the filter sidebar or at all on mobile. You have to go into the actual search function and if you're on mobile, it won't even show you the results, just the number; as if you've muted every user.

Unavailable on Firefox mobile.

Works as expected, took me a minute to figure out that you had to go through the actual search function rather than the filter sidebar. Would be cool if there was a checkbox there as well, as I think most people use that more often than the search feature. :)
