uBO-Extra

Still, installing uBO-Extra is a damn good idea. If nothing else than to block insidious methods such as Instart Logic and WebRTC abuse: https://github.com/gorhill/uBO-Extra/wiki/Sites-on-which-uBO...

Also highly recommended for people who are willing to spend a little more time to control where their browser retrieves content is uMatrix[1]. Written and maintained by the most esteemed Raymond Hill who creates uBlock Origin. If you're on Chrome, don't forget to also install uBO-Extra[2] along with uBlock Origin[2], otherwise you don't get WebSocket coverage.

This really depends on the lists that you use in each. Research exactly what you want to block. I personally don't like a few of the lists for that specific reason, they block everything all together, not just tracking pixel domains and things of that nature. There is also an official uBlock Origin Extra extension that I find very handy for blocking websocket garbage. This is becoming more important as websocket connections become more prevalent. https://github.com/gorhill/uBO-Extra/wiki/Sites-on-which-uBO...

Sites do this. For example, see Instart Logic: https://github.com/gorhill/uBO-Extra/wiki/Sites-on-which-uBO...

It's referenced in the OP: Chromium-based browsers are being “infested” by Instart Logic tech which works around blockers and worst, around browser privacy settings (they may start “infecting” Firefox eventually, but that is not happening now). And there is a link to further elaboration: https://github.com/gorhill/uBO-Extra/wiki/Sites-on-which-uBO...

Also: > The purpose of Instart Logic technology is to disguise 3rd-party requests as 1st-party requests, thus bypassing content blockers, and even the ability of browsers to block 3rd-party cookies (because they are stored as 1st-party cookies): https://github.com/gorhill/uBO-Extra/wiki/Sites-on-which-uBO...
