NordicFiltersABP blocks practically everything on many sites

[Komposten]

Describe the problem below this line as meticulously and detailed as possible (incl. pagelinks if any)

Since today (13/2 2025) the NordicFiltersABP list appears to block almost every single request on GitHub, AWS, Microsoft, Slack, localhost, etc.

Tested with Vivaldi's built-in ad blocker and ABP in Google Chrome.

I'm having the same issue as of today. Most sites fails to load correctly, or at all, with Nordic (Dandelion Sprout's Nordic Filters) checked in Vivaldi's ad-blocker. Sites loads as expected with it unchecked.

I went through the history of changes from the latest update, looks like it might be line 2054 in NorwegianExperimentalList alternate versions/NordicFiltersABP.txt that's the culprit, but I don't know for sure, just looks like a wildcard that'd capture all pages:

adfilt/NorwegianExperimentalList alternate versions/NordicFiltersABP.txt

Line 2054 in bd54042

Ye, my own little investigation led me to that line being the culprit as well.
I've tested and verified it working with this fix by importing locally in Vivaldi.

Idea: Add a basic Github action that runs on push/pr/... that does something like grep -P '^\*$' $filename && return 1
