Describe the feature you'd like to see added
Sadly I got limited by the size of the cookie when I tried to, but I have a list of 1 000 + SEO domains / github hijacking result etc. I would have had banned for a better user experience.
Could it be possible to append a file of banned domains for instance such a list as a line or comma separated format : https://github.com/quenhus/uBlock-Origin-dev-filter ?
