    And they recently released the Safari MCP in STP as well.

    Looks like the Safari MCP is also now available in the most recent Golden Gate beta part of system Safari:

    The team has been on a roll lately with massive fixes & improvements.

    Like last months announcement of over 500 fixes.

      The Safari beta is actually covering ~6 months of work in WebKit. So it isn't one release with 500 fixes. It is more of a consolidation.

      But yes WebKit has been getting tons of feature gap and bug fixed in the past 2-3 years. I think it accelerated during Safari 17, and Safari 18 has been the release that I find it good enough for most cases and finally with no rendering issues on all the site I browse.

      I have been trying to get the release note and update from Safari on HN frontpage but it never got much attention. Hopefully like you others will see how far Safari has come. And out of all the features coming from new macOS releases it has always been Safari that I am most looking forward to.

      At the same time I still think it has some way to go before catching up to Firefox and Chrome is many areas. But at least it is improving fast.

      They finally used some of those trillions to buy one (1) Claude pro subscription.

        It's because the EU is forcing competition on them for iOS Safari, and iOS Safari shares code with MacOS Safari. Now they have to at least try to keep up.

        • SaltyBackendGuy a day ago ago

          I am OOTL - How does the EU force competition in this context?

          • fragmede a day ago ago

            The EU passed laws to force Apple to allow other browser engines to run. Previously, all iOS browsers were reskinned WebKit by Apple decree.

            • ulfw a day ago ago

              And is there any other browser engine actually running on iOS anywhere?

  • CuriousRose a day ago ago

    Safari is the only real opposition to Google based browsers at the moment. Yes Firefox is a contender, but it has no brand traction among non-power users. Google has the brand, Safari has the defaults and energy efficiencies of the growing Apple laptop/desktop market. Although not open source, I trust it far more that a Google based browser as Apple - aside from PWAs competing with their App Store - has no real incentive to commodify, restrict or surveil the web like Google does.

    • owebmaster a day ago ago

      > aside from PWAs competing with their App Store

      Yeah. Aside. Let's just ignore that Apple intentionally prevents users from using the browsers most needed feature for the common user today killing it just like they killed Flash.

      • pjmlp a day ago ago

        Thankfully, otherwise the Web would already be ChromeOS Platform, because that is what 99% of the folks that don't use Safari would install.

      • nozzlegear a day ago ago

        Intentionally how? Mobile Safari has pretty broad support for PWAs: https://pwascore.com

        • owebmaster a day ago ago

          It does not. It doesn't support the installprompt event and hides the "add to home screen" behind 4 actions/clicks to make sure the users don't easily install PWAs.

          • nozzlegear a day ago ago

            So one missing thing is enough to decide that PWA support isn't broad and Apple doesn't care about them, despite all those supported PWA APIs?

            > behind 4 actions/clicks to make sure the users don't easily install PWAs.

            I maintain a PWA for retainer client. Our website has a paragraph telling users how to install the PWA via the share button. We'd have a paragraph telling them how to install it from the App Store too if it weren't a PWA.

            • dylan604 a day ago ago

              I think the fact that the paragraph is necessary is the damning part

              • nozzlegear a day ago ago

                Like I said, we'd have that paragraph even if the app was on the App Store. If it's damning, then it only damns the users because they're goldfish.

            • owebmaster a day ago ago

              One missing thing? You think Apple forgot to implement the install event? Or that there is some technical reason?

              • nozzlegear a day ago ago

                No, I'm asking if that's the one thing you're hung up on? I feel like that was obvious.

      • leejoramo a day ago ago

        On macOS i use Safari for PWAs. It is just fine.

        But I use Firefox as my primary browser. PWA support non-existent. They killed their basic PWA support many years ago. There are suggestions they will support it in the future.

        On Linux/Windows, I use Brave for PWAs.

  • Affric a day ago ago

    Since they nixed uBlock Origin Safari has not been a serious web browser to me. No amount of technology can make up for it.

    • paddingtone a day ago ago

      I've been using uBlock Origin Lite on Safari with no issues.

      https://apps.apple.com/us/app/ublock-origin-lite/id674534269...

      • jvican a day ago ago

        I use Adguard/wipr to great success. Why's uBlock Origin better? Also, wipr now has filtr, which provides URL filtering at the macOS level, so it's as efficient as it gets.

        • arijun a day ago ago

          I think the limitations are similar to the manifest v3 issues that the Chrome version has. Specifically, you (the ad blocker) send the browser a list of sites to block, instead you blocking them yourself. That means it's way harder to do clever things like scriptlet injection to find ads and get around adblock detection.

          • whstl a day ago ago

            Not true in Safari. uBlock Origin Lite doesn't have those problems.

        • kstrauser a day ago ago

          Seconded for Wipr. It's my favorite adblocker I've tried yet (although 1Blocker is also really nice). And if the author sells it to some creepy company, the Safari API means that the new owner can't spy on my viewing. I'm not sure how it could be materially improved by using less privacy-respecting APIs.

          • flyingshelf a day ago ago

            > the new owner can't spy on my viewing

            Quick question: how do you distinguish content blocker extensions from regular extensions? All the Adblockers I know have to use both to be effective at hiding ads, especially on YouTube.

            In that case, the new owner can still do the spying.

            • fizwidget a day ago ago

              In iOS at least, it tells you in Settings > Safari > Extensions. E.g. if I tap into one of the AdGuard ones I see:

              “"AdGuard — General" does not have permission to read or transmit content from any web pages.”

              Ones that have more permissions will say so.

        • jjice a day ago ago

          I use AdGuard, Wipr, and uBlock Origin Lite on my iPhone, and uBlock Origin on desktop.

          I swear there are little gaps in each that the others get, but they're very minor. When uBlock Origin Lote recently released on iOS (within the last year), I noticed a few more things blocked. I also prefer the custom element removal or uBlock and can reuse my desktop filters.

          It's free, so I'd recommend adding it as an addition to the bunch.

      • JSR_FDED a day ago ago

        1Blocker has been rock solid for me. Got it after reading about it on Daring Fireball and now I can’t use a Mac without it.

      • faizmokh a day ago ago

        Agree. I've never seen any single ads so far.

        Even the ads on the Youtube are block by default. It's quite buggy though.

      • zarzavat a day ago ago

        This doesn't solve the problem. The whole point of uBO is that it plays the cat and mouse game between adblocking and anti-adblocking.

        If you are OK with sites blocking you when you use an adblocker then there's a multitude of other options.

  • argee a day ago ago

    Does this help stable Safari in any way? I have a WebKit bug I’m tracking that’s fixed in STP but not in stable and it seems like there’s no telling whether it’ll ever land.

    • lapcat a day ago ago

      It'll land eventually. They always do, though maybe months down the road. But of course Apple won't preannounce its plans, and unfortunately I'm not aware of a way to track WebKit commits in specific Safari releases.

  • exabrial a day ago ago

    Please, can we put the "Disable Javascript" menu back in the Developer menu

  • kqp a day ago ago

    Anybody know how to get Safari to “sanitize” on shutdown (delete cookies, cache, etc), except for whitelisted domains? After lots of fiddling I’ve realized this is probably the best privacy/convenience compromise for me, but Safari is the only browser I can’t even find a plugin to do it in.

    • dylan604 a day ago ago

      s/Safari/Firefox/ and it is super simple to do this. I know that's not helpful to the question as asked, but possibly a better answer???

      As for Safari, closest I see is Preferences -> General -> Remove History Items. It has options ranging from After One Day, one week, one month, never. I don't see an option for at quit like FF has.

  • robrobrobrob a day ago ago

    Please add way to maximize the window. I rage quit when it goes fullscreen or just tall.

    • woodson a day ago ago

      Try option-click on the green icon in the app window. It’s well hidden and unintuitive, but I think it does what you want.

      • rwc a day ago ago

        (bonus: this is not exclusively a Safari feature, this is a macOS feature)

      • robrobrobrob a day ago ago

        option click does not fully maximise!

    • HaloZero a day ago ago

      I just use Rectangle. It's got all the core functionality. https://rectangleapp.com/

    • norgie a day ago ago

      Fn-Control-F or hover over the green dot and pick the maximize option

      • robrobrobrob a day ago ago

        omg it works.. why is this so hard?

    • pupppet 14 hours ago ago

      I hate this default behavior on the green button. I can count the number of times I've intentionally wanted a full-screen app on one hand.

  • geerlingguy a day ago ago

    The one feature I would love to see is WebSerial support, now that Firefox has it too.

  • nikanj a day ago ago

    It’s impressive that pinch-zooming reddit.com in-out-in-out has reliably crashed ios safari for at least a few years already. One would assume Apple gets telemetry from iphone default browser crashes, and reddit seems important enough to warrant a fix

    • lapcat a day ago ago

      This was fixed but then reverted. No further updates 3 months later. https://bugs.webkit.org/show_bug.cgi?id=305622

      Not sure how this comment is related to Safari Technology Preview, though, which is Mac-only.

      • steve1977 19 hours ago ago

        On the other hand, Reddit is trying so hard to funnel users to their app that this bug might solve itself at some point.

      • nozzlegear a day ago ago

        Kind of a confusing title, but maybe it means more to the WebKit team. I don't think I've ever seen jetsam used as a verb before.

      • nikanj a day ago ago

        The only way for commoners to reach the actual devs is HN or similar, bug trackers are as useful as a wishing well.

        The odds of Safari devs reading the comments on a Safari-related HN piece is quite high, and reporting long-standing bugs here might actually get fixes

        See also: the biweekly ”Microsoft closed my account and is stonewalling me” post here. Those reliably manage to break the customer service blockade

        • lapcat a day ago ago

          > The only way for commoners to reach the actual devs is HN or similar, bug trackers are as useful as a wishing well.

          This is untrue for the WebKit open source project. Many of the bugs I've reported via the Bugzilla have been fixed.

  • bearjaws a day ago ago

    I cannot use a browser that is owned by a company who's financial model is dependent upon browsers being nerfed.

    Apple and Google have far too many incentives to wall garden browsers, Apple due to the app store, Google due to advertising.

    Independent browsers are the only safe path forward.

    • wpm a day ago ago

      Funny, I prefer to use Safari because it is just a damn web browser and isn't trying to let every webslop dev try and re-invent the wheel in slow JITed Javascript and build their own crappy operating system. Whatever their reason, Apple is the enemy of my enemy, and therefore, in this regard, my friend.

    • SJMG a day ago ago

      Well this preview includes many changes made to WebKit which Kagi, a so called independent browser, depends on. It's good news for you.

    • gausswho a day ago ago

      You're correct. Which makes it all the more inscrutable that the Firefox team doesn't embrace PWA's as a differentiator.

    • dbbk a day ago ago

      What did they nerf

      • bearjaws a day ago ago

        Apple: adblocking, PWA being put in a odd spot, surely to be followed by a post "nobody was using it" before being removed, if they mention it at all.

        Google: ad blocking

        • dbbk a day ago ago

          Ad blocking isn't nerfed

          • arijun a day ago ago

            It is when compared to Firefox. Safari and now Google claim that it's for security, as the newer interfaces expose way less attack surface for malicious add-ons. I think that it's true that it does improve security, although I'm not sure that I believe Google when they say they're not doing it to stop people from blocking their main revenue source.

            • whstl a day ago ago

              At least the blocker I use, uBlock Lite, isn't nerfed. It doesn't have Manifest v3-ish limitations, and can do dynamic blocking, injection, etc.

              • arijun a day ago ago

                It cannot do dynamic filtering [1]. Another big one I forgot about is no CNAME uncloaking. Don't get me wrong, uBOL is still a great add on, it's just not possible to do everything you could with the manifest v2 version.

                [1] https://github.com/uBlockOrigin/uBOL-home/wiki/Frequently-as...

              • eipi10_hn a day ago ago

                uBO Lite is exactly MV3, it has most of MV3 limitations plus its own limitations comparing to Chromium. Safari just auto converts MV3 codes to Safari's own blocking engines.

      • unsungNovelty a day ago ago

        PWA for starters? They are not interested in Indie devs anyways. Might as well let us use PWA no?

      • EPWN3D 18 hours ago ago

        Nothing. This is just FUD.

    Wonder if they will ever fix upload progress using XHR, pretty annoying to not be able show accurate progress to the user when using larger chunk sizes:

    https://bugs.webkit.org/show_bug.cgi?id=277286

  • lapcat a day ago ago

    This update fixed some web inspector bugs that I reported, but I can't use it because Safari Technology Preview inexplicably supports fewer macOS versions than Safari itself, i.e., no longer Sequoia.

    • kstrauser a day ago ago

      I don't know, given that Safari is bundled with the OS, targeting a newer macOS seems pretty explicable.

      • lapcat a day ago ago

        Safari supports 3 major macOS versions. For example, Safari 26 continues to support Sonoma and Sequoia as well as Tahoe: https://support.apple.com/en-us/127685

        Safari 27 will support Golden Gate, Tahoe, and Sequoia. However, Safari Technology Preview now supports only Golden Gate and Tahoe, despite the fact that the same WebKit commits will make their way into regular Safari on Sequoia. Thus, it seems that Apple is just shooting itself in the foot by failing to test sufficiently on one supported platform.

  • majima a day ago ago

    if only they bring back safari to windows

  • JSR_FDED a day ago ago

    After being so disappointed by Tahoe and the whole Alan Dye era, it’s great to see Apple getting their mojo back. Golden Gate is shaping up to be a great release.
