I don’t understand what did you intend to respond to with this. as filtering instructions get more out of date, the addon’s privacy protections will also fail.

OK, I get what you mean. I guess if you require 100% certain and absolute privacy, then yeah, uBO is the way to go. Seems like a pretty narrow user-base, tho.

on youtube? if you fire up firefox, install uBO, ocannote uBO logger and open a youtube video page, you’ll see what it does. I don’t know what it does different because I don’t happen to have an itemized list of what does uBO lite do, but I suppose it has a logger function too, and you can compare it.

If there is a difference, it's not noticeable to me. I fired up YT on FF with uBO and then the same video on Vivaldi with Ghostery. Honest to God, I do not see it loading longer on Vivaldi.

to set variables used by youtube, to unfuck youtube in other technical ways, and to block behaviors it shouldn’t even think about doing (why does it need a scriptlet that blocks writing the clipboard??), blocks ad video segments, hides annoying things from the UI because I have lists enabled that do that.

Most of this sounds like I get in Ghostery too. Blocking specific HTML elements is the one feature I feel is missing from Ghostery, but that's not really an adblock/privacy feature, is it?
