@Euphemism8917 Easylist is already part of Shields. Not sure if trying to add an existing could be problematic or what’s going on. I’m not going to try to add at this point to see if can replicate. Guess can tag in @Mattches just to see if he can bring clarity in that regard. But will say Brave uses the below by default:
Brave First-Party Specific
Brave Social
Brave Specific
Brave Unbreak
EasyList
EasyPrivacy
Online Malicious URL Blocklist
Peter Lowe’s Ad and tracking server list
uBlock filters – Ads
uBlock filters – Badware risks
uBlock filters – Privacy
uBlock filters – Unbreak
Yeah, it’s innate parts of it that can’t be removed/disabled. You can kind of confirm for yourself by checking out https://browserleaks.com/proxy which kind of checks to see what content filters are in use by people. You can try to enable certain ones and go back, you’ll notice it reflected.
