SUMMARY Please consider adding support for uBlock Origin lists. The code exists (see below). uBlock Origin lists are much more effective in filtering certain ads and anti-adblocker nag screens. STEPS TO REPRODUCE 1. Try to add the first 4 lists from https://github.com/LeFroid/Viper-Browser/blob/123305d7f2f8f323f8672e16071f4cb4f55be3b1/src/app/assets/adblock_recommended.json OBSERVED RESULT uBlock Origin lists cannot be used. EXPECTED RESULT uBlock Origin lists can be used in addition to Adblock Plus lists. ADDITIONAL INFORMATION https://github.com/LeFroid/Viper-Browser/ has the code needed for uBlock Origin lists.
