iOS Safari has supported declarative content blocking extensions since iOS 9 in 2015 and a full extension API since iOS 15 released about two years ago.

    Oh I'm sorry, is this a five minute argument, or the full half hour?

Declarative blocking is the weakest, it barely removes the simplest ads. uBlock doesn't exist for iOS because it is made impossible by apple, their extension API is not a "full" API.

  I haven’t seen ads on mobile Safari for as long as I can remember. Whether you choose to believe that is up to you. Can you point to an example where an extension like AdGuard would let an ad slip through? Precompiled declarative blocking is more performant and power efficient than running a content script in a JS VM at page load, which matters on a CPU and battery constrained device. I was responding to a comment claiming that mobile Safari doesn’t support add-ons. Which is simply not true!

    If anything, my problem is sometimes it’s too strong. Searching for a product on Google and clicking the Amazon links don’t work

    It's not only the ads slipping through. Safari is so lacking in terms of API that for many sites with anti-adblock, the only way to bypass those are allowing tracking / ads connections. Check the `@@` filters for `ios` here: https://raw.githubusercontent.com/AdguardTeam/AdguardFilters/master/BaseFilter/sections/antiadblock.txt https://raw.githubusercontent.com/AdguardTeam/AdguardFilters... Adguard's default settings already do not include many tracking connections blocking filters, due to the lack of Safari's API for redirecting to neutered sources which could easily lead to breakages / anti-adblock. In terms of privacy-protection, Safari is one of the worst.

    > Can you point to an example where an extension like AdGuard would let an ad slip through? Yes, see Twitter. I have AdGuard installed on iOS and I do see ads. I do not see them when opening on Firefox desktop with uBlock Origin. If I disable uBlock then I do see them like on Safari. As I said, precompiled declarative blocking only works for the weakest of blatant ads. Of course it's "more performant and power efficient" because it only runs on the bare HTTP requests. That's not what I want. > I was responding to a comment claiming that mobile Safari doesn’t support add-ons. Which is simply not true! Fair enough. But personally I don't count Safari's extensions as real extension, just like I don't count Firefox' previous approach of a handful of "blessed" extensions for Android as real extensions.

  uBlock doesn’t, but plenty of browsers have built-in adblocking, with one of the very browsers missing it being.. drumroll.. iOS Firefox! Mozilla refuses to address how having no adblock is a security risk, so I have moved all my friends and family over to iOS Brave. Firefox built its own demise by having a bizarre focus on woke stuff instead of features that users direly need.

        - Firefox has been pumping out bizarre woke-language filled blog messages, the annoyance at this has even been upvoted to #1 on the frontpage of HN - Firefox iOS has no real adblocking - Mozilla has an issue for this open on both their Github and Bugzilla for years - Firefox Focus does have real adblocking built in Maybe trolls like you should leave HN :)

    iOS Firefox is just a re-skinned Safari, just like iOS Chrome because Apple has some rule against "dynamic code execution" in their AppStore. Which sure is nice to combat some malware but not really MY problem. It also coincidentally happens to also rule out ANY browser engines. Firefox and Chrome can only use the provided webkit "WebView" component. Apple has effectively crippled Browsers on iOS to Safari, or a worse re-skinned version of Safari.

  I’ve been using 1Blocker since day one and have nothing but praise for their product. Not as powerful as uBlock Origin, but pretty good nonetheless.
