Wildcards in uBlock websites not working

I use uBlock0 on Firefox 40.0.2 and I the filter *.stackexchange.com###hot-network-questions in "My Filters" does not remove the element. When I replace *.stackexchangewith academia.stackexchange, for example, it removes it as intended. Does uBlock not support wildcards or do I need a different syntax? .* instead of * does not help as well.

Solution 1:

Your filter *.stackexchange.com###hot-network-questions is not an Adblock Plus-compatible filters -- see Adblock Plus filters explained.

You do not need to use a wildcard: stackexchange.com###hot-network-questions will work on stackexchange.com and all subdomains of stackexchange.com.
