According to the newest (2025-08-12) privacytests.org test it is pretty good but for desktop Mullvad Browser and Tor Browser are best.
As for Android: Tor Browser and Firefox Focus were best at that time though neither block advertisements. Firefox Focus does not support installing add-ons and it is highly recommended not to install one in Tor Browser as it will make you stand out from the rest of its users.
Personally I can recommend Ironfox to you. It is the continuation of DivestOS’ Mull Browser (not Mullvad). It is hardened Firefox and asks you on first launch if you would like to install uBlock Origin. I presume most people tab on ‚yes‘, so not installing it would actually make you stand out
I can’t even access the mullvad website or DNS anymore. I’m assuming they haven’t shut down and it’s my isp blocking it (got switched from talktalk to virgin media) and the opera vpn doesn’t work anymore either (I just use it when I need to get around geoblocks) but I don’t know if that’s on their end or mine.
For some reason I’m blocked by reddit on opera on both desktop and mobile, but I can view it on ddg. There’s definitely something weird about opera.
I have librewolf with ublock origin on desktop. I recently installed ddg desktop as well.
I’m putting my faith in the DDG tracker blocker feature, but tbh I have no idea if it actually works or not.
