In light of Heardle’s recent April Fools prank, it seems as good a time as any to make my uBlock rickroll filter list known.

To use the filter list, which blocks 156 variations of rickroll videos as of this writing (DM me if you find one that isn’t included), simply add the following URL as a Custom uBlock Filter:

https://fewrx.net/rickrollfilter.txt

After importing the list, visits to any youtube.com or youtu.be URL containing a known rickroll video ID will be blocked.
