Firefox for iOS Gets Built-In Ad Blocker

Mozilla today said it is adding an ad blocker to Firefox for iOS, allowing users to block many third-party ads and ad-related trackers.

The ad blocker uses the EasyList filter list and Apple's WebKit Content Blocker technology, which is the same content-blocker API Safari ad blockers use. App Store ad blockers only work with Safari, so Mozilla built the feature directly into the app.

Firefox won't block ads served by the site you're visiting, and ads shown in search results will still appear. Sponsored shortcuts and other sponsored content shown by Firefox when you open a new tab are separate from ads and won't be blocked.

Ad blocking is turned off by default, and it can be turned on in the Firefox app by going to Settings > Browsing > Ad Blocker.

RIP, MacBook Ultra

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

Does it end up blocking anything?

I get the point of desktop Firefox but iOS Firefox is just wrapped WebKit
Which is why them adding a built in AD blocker is nice!

I'd love to be running a full blown FF on mobile, but Apple won't allow it.

The reason to use it is it syncs up smoothly with my desktop and has niceties like "open a tab in FF on another device", etc. I do that one a lot actually. It's really nice when I see something on my phone I want to dive into on my Mac to just shoot it over to a new tab on my FF Mac install so I don't forget it.

I'd only recommend FF mobile usage if you also use FF on desktop as I do.

Too bad Safari doesn’t have this natively. Besides the ad blocker, don’t forget the lovely:

SponsorBlock — automatically skips the “This video is sponsored by…” slop.
DeArrow — gets rid of those ridiculous clickbait YouTube thumbnails and replaces them with more accurate ones based on the actual video.

The only one left standing is a general short-video slop blocker. Haven’t found a decent one yet.

Is it blocking anything in the end?
I think they mean to say that ads that are served by the website themselves won't be blocked, this is pretty typical of ad blockers. Ads served by third parties will be blocked
