To add… if you install the DuckDuckGo browser app on your android phone, it will block all the trackers in your other apps!
Fair warning though, you will likely feel a bit of shock & horror to find out just how often you’re being tracked, and what sort of data these apps are sucking down relentlessly and constantly. Even the ones you haven’t used for a while.
Blocking variations.brave.com which is used for A/B testing could potentially break Brave's functionalities. For me did Brave's "forgetful browsing" feature broke which seems to be disabled by default if you block this domain.
Little Rat - a browser extension for monitoring other extensions
"Little Rat is an open-source extension designed for network traffic monitoring. Easily view, monitor, and block traffic from other Chrome extensions on a per-extension basis."
I use it myself and I think it's a very useful extension for everyone who uses more than just few extensions for different purposes and don't fully trust them that they send no data as the developer promises, this extension can monitor the network and act as a firewall per-extension basis.
Isn’t piling on browser extensions generally considered bad practice as it increases your attack surface (bad for security) and makes you more easy to fingerprint (bad for privacy)? This seems like a useful tool to use and then uninstall, but if you don’t fully trust something then you shouldn’t really be installing it at all!
