Don't run multiple general adblockers (e.g., uBlock Origin and AdGuard) simultaneously to avoid breakage. Combining general adblockers with tools like SponsorBlock is fine.

Always check extra uBO filters in settings before trying third-party filter lists.

If your goal is to block browser ads, it's best to just stick with uBlock Origin, as additional filters can cause conflicts or anti-adblock.

Outside of WARP it's generally best to use a paid VPN, especially if you have privacy or speed in mind. Free VPNs are mostly useful for things like unblocking websites.

Keep in mind many proxy sites log info like IP address, sites visited, etc. They're useful for unblocking sites, but not very useful for privacy.
