The proposed way for content blocking in Manifest V3 is how Safari on iOS implemented it a few years ago — a declarative list of URLs to be blocked is provided by the extension and the browser engine looks that up and blocks them. The extension doesn’t see the actual page URLs or requests, leave alone block them.
This is a positive for privacy since the browsing behavior of the user is not exposed to malicious extensions. But uBlock Origin is not some-random-extension-that-wants-to-steal-information. Treating uBlock Origin like any other extension isn’t good. Since Google makes money by selling ads, there will likely not be any concessions on this front.
There is no win for privacy here.
Try to use Youtube without an ad blocker. It's insane.
It's very common to see: "Ad 1 of 2", the first of which is unskippable, the second of which needs 5 seconds to be skipped (if it's skippable at all). Then you get the content which is almost always sponsored and opens with an ad of its own "this video sponsored by squarespace" etc;
A deluge of marketing, and somehow "not profitable". I don't get it.
Caveat: I was using Firefox Developer Edition... I wonder if "normal" FF would be better.
Disclaimer : I use about 6 privacy focused addons in total.
I tend to be very frugal in my use of tabs, maybe 30 at any one time and even then very briefly and I don't have any issues.
To put this in perspective, I'm on a Librebooted T400 machine, so 4GB RAM on a Core 2 Duo and it FF hasn't been a major issue at all. Everyone's mileage may vary.
Why? Doesn't it work with Firefox?
