Unless by built in, you mean the ublock that comes with librewolf, thats fucking stupid. Adblocking is an armsrace that requires constant up to date collaboration on the adblock developer side. Thats why you need crossplatform plugins like ublock, otherwise you will end up seeing ads.
Vivaldi browser also has a built-in ad blocker on all platforms, but the PC/Mac/Linux version also allows you to use uBlock Origin as well (at least until mid-2025).
I did not call you stupid, i called the things that you wrote stupid. Those are two very different things. You called the best practices, recommended for any user that wants to safely use a normal web browser, "fear mongering". That is in fact a very stupid thing to do.
No, Vivaldi, Brave and Opera have builtin adblockers which don't depend on the extensions manifest. Plus, one could always rely on AdGuard, which whould block ads system wide.
Firefox is a browser, not an adblocker. Why would they make their own adblocker when there are already independent adblockers that are very good? I would suggest Firefox just come pre-installed with uBlock Origin
I don't justify Mozilla's bullshit, and I don't use upstream Firefox for that reason (I use LibreWolf). Asking Mozilla to implement their own adblocker is asking them to reinvent the wheel. They should ship Firefox with uBlock Origin pre-installed like I said. Asking Mozilla to write their own adblocker which will likely be less effective than a third-party adblocker, is absolutely not the same thing as justifying them sneaking in opt-out PPA. How on earth do you even see those things as remotely comparable
I'm saying that your suggestion is ridiculous, not that what Mozilla is currently doing is correct.
Or you could stop raging about the only choice we have against a browser monopoly. You don't have to make up excuses to hate it and then broadcast them to an audience who mostly disagrees
I've done tests with the built-in Firefox strict mode vs uBlock and there's a bit of a difference. Firefox blocks about two thirds, uBlock is almost 100%.
