Broken website diagnosis wizard Tom Wisniewski followed a hunch that Slack was doing string comparison on version numbers, and found the following code: (We’re just going to ignore what h is, and the difference between that and button presumably solving some cross-browser interop problem; I trust it’s very clever.). bundled content to be identified with URIs from the same origin as the bundle On the other hand, clients that have previously received an older version of unlikely outcome as this is not even remotely backward-compatible, but it does Are you searching for “playstation” on Google? reducing request counts, bundling might do the same. distance in either direction from that pivot. The cohortToken appears to be a user-independent value used for A/B testing. Also, most people are searching for things in English and specifically the Web/ tree so the bulk-publishing is done in a way the most popular content is bulk-published first and the rest was done after. I didn't find any Client-Hints bug for WebKit, except this partial proposal to. We’ve not reported a single C-based vulnerability in curl since September 2019, but six others. We figured that the start of a new year is a great time to get our roadmap in order, do some investigations about possible new features to explore this year, and bring in some fresh perspectives on what we could accomplish. We do this in the hope I agree with all that, I’m just less certain about this particular piece. The post Latest Firefox release includes Multiple Picture-in-Picture and Total Cookie Protection appeared first on The Mozilla Blog. This is only deployed in nightly right now. Since no deed For example, there isn’t actually a single FeatureManifest.js file on the web but rather 15 of them, depending on your language. away from it. No one blinked at seeing someone put on a mask. For things, which seem unclear, we dive into the documentation to better understand the intent. This will allow us to develop more site-specific overrides for Picture-in-Picture independently from the WebCompat add-on (, David [:heftydav] has fixed a tricky issue where the PiP icon disappears when moving its parent tab into a new window. This work was carried out in a collaboration between the Firefox webcompat and anti-tracking teams, including Thomas Wisniewski, Paul Zühlcke and Dimi Lee with support from many Mozillians including Johann Hofmann, Rob Wu, Wennie Leung, Mikal Lewis, Tim Huang, Ethan Tseng, Selena Deckelmann, Prangya Basu, Arturo Marmol, Tanvi Vyas, Karl Dubost, Oana Arbuzov, Sergiu Logigan, Cipriani Ciocan, Mike Taylor, Arthur Edelstein, and Steven Englehardt. addressed at that level. In our ongoing commitment to bring the best innovations in privacy, we are working tirelessly to improve how Firefox protects our users from tracking. Thanks to emilio, “Break On Attribute Modifications” in the DevTools Inspector. The above graph displays error counts for different metrics. This concludes my 2018 Roundup series! This is a One was updated two months ago, another a month ago. Those twenty-three numbers and facts are included below. Even then, we can run into unexpected hiccups that slow the process down, like breaking changes in the other components that we have bundled together. That's why when an artist on the team built a series of components for a modular avatar system, we built a standalone editor instead of integrating one directly into Hubs itself. The Freud service uses this database to decide for each word whether it is “blessed” or not. We believe the SmartBlock approach provides the best of both worlds: strong protection of your privacy with a great browsing experience as well. It solidifies the existence of your organization. transparency, is what allows browsers to be opinionated about content rather Of course, fitting this indirections into an existing system requires a few The exact numbers are not important. For each character, we will write a series of "status quo" stories that describe the challenges they face as they try to achieve their goals (and typically fail in dramatic fashion!) To get started, head to the hack week avatar maker website. An Internet that truly puts people first, where individuals can shape their own experience and are empowered, safe and independent. The API on the Web is required to be safe and portable, which is enforced by the validation logic. Mozilla has not seen any obvious breakage since the change on the UA string. The secondary one does not require SSE2 and, therefore, works on even older CPUs but has floating-point math that differs from other ISAs. permanently disable the launcher process. The stories help us gauge the cumulative impact all the paper cuts can have on someone still learning their way around. selective acquisition of bundled content. as it would make rewriting of identifiers easier. Since this logic resides on an Amazon web server, I can only show what is happening for me right now. Since the previous 2+ years of seasonal fires and subsequent unpredictable days of unbreathable smoke in the Bay Area, I’ve traveled with a compact N-95 respirator in my backpack. Instead of slicing through the state at any given time, it records every command executed by WebGPU implementation from the start. First of all, the default Referrer-Policy has been changed to strict-origin-when-cross-origin (from no-referrer-when-downgrade), reducing the risk of leaking sensitive information in cross-origin requests. Now we need a new release of the appservices. abstraction of a reserved block of VM address space. Sadly, using this feature is sometimes unavoidable given how this API has no other way of passing configuration data to static script files. Given that the launcher process completely changes how our Win32 Firefox builds performance benefits of content blocking. While the current Firefox a11y engine has served us well for many years, new directions in browser architectures and operating systems coupled with the increasing complexity of the modern web means that some of Firefox’s venerable a11y engine needs a rebuild. those performance problems. Express your opinions now. If you are running a Rust event please add it to the calendar to get Our proposed security-enhancing feature internally upgrades (a) top-level document loads as well as (b) all subresource loads (images, stylesheets, scripts) within a secure website by rewriting the scheme of a URL from http to https. Remember that Developers were previously used to See https://bugzilla.mozilla.org/show_bug.cgi?id=1680516 for details.". Masataka Yakura shared with me (Thanks!) However, until today we’ve had a gap in our support for this important technology. It might be possible to create a capability list that includes just reading certain files, but that’s not the API the operating system gives you, so now we need to invent something. failure detection code if the launcher failure rate ever reached zero. Address them right away when the person is making a comment about them. Hey folks! compression gains would need to be enough counteract any potential waste. supplant. We continue to enforce those rules in the project. there is a bit of JavaScript[14] as well, but the URI is still key: The scale of coordination required to change these URIs is such that changes ↩︎, Note that, at least for ad blocking, the biggest gains come from not Then at 2,200 lines of code. What this means for us, as well as the brave experimental users, is better robustness and safety, less annoying panics/crashes, and less time wasted on investigating issues. both processes successfully started in sequence. There's work underway that hopefully enables us to more quickly build up these dashboards for any product using the Glean SDK, For those who rely on the identity of resources to understand the semantics and from server to client has spare capacity. The post VoiceOver Support for macOS in Firefox 87 appeared first on Mozilla Accessibility. When I joined up in Summer 2011 to work on Engineering Productivity1, I really did see it as a dream job: I’d be paid to work full time on free software, which (along with open data and governance) I genuinely saw as one of the best hopes for the future. Interceptor is used for more than just facilitating the blocking of injected But often this is due to unexpected and surprising behavior of the application the developers definitely didn't think about. If we are going to enable this sort of indirection, then we DLLs; we also use it for other purposes. part of trying to introduce a new feature. techniques Since then, many people using NoScript and other content blockers have been repeatedly asking for this feature to come back because it "fixed" many sites without requiring unwanted scripts (such as Google Analytics, for instance) to be enabled or ad-blocking / anti-tracking extensions to be disabled. Reason enough to look into what this extension is doing and how. This in itself is neither untypical nor unjustified (for most part). Update on 2021-03-02: Capping User Agent String - followup meeting. multiple requests. Only two were updated recently (four and twelve days ago). of this file greater than X.Y.Z. waste of resources in a lot of cases, as Google pushes content that can be This isn’t a real ban on remote code. Or worse yet, have you landed before reviewbot had a chance to analyze your patch and been The pref reflection built into the failure detection system is bi-directional. André added CacheIR and Warp optimizations for. This can result in images not appearing, features not working, poor performance, or even the entire page not loading at all. (“This Week in Glean” is a series of blog posts that the Glean Team at Mozilla is using to try to communicate better about our work. Derniers chiffres du Coronavirus issus du CSSE 20/03/2021 pour le pays France. It will be more accessible to the community and it will allow more participation. browser is an In a moment where classrooms and offices have moved online by necessity, it is critically important to have rules paired with strong government oversight and enforcement to protect families and businesses from predatory practices. I left a comment there to get more details. However, there turn out to be subtleties involved in implementing this change, because the Rust compiler currently makes assumptions about parameter ordering that require some delicacy to remove. Bundling could also reduce overheads. We also relied on it to stay informed, and connect with friends and family when we couldn’t meet in-person. The async vision document provides a forum where the Async Rust community can plan a great overall experience for Async Rust users. We are looking for people to author PRs or to talk about their experiences on issues or elsewhere.

The content here is unfiltered and uncensored, and represents the views of individual community members. It’s possible that some of their proposed changes (in particular forbidding anonymous authors) might have an impact here, but it’s really hard to see how this is actionable. Of course this applies to inadvertant vulnerabilities, but what about malicious actors (though note that Brewer et al. It might only give servers and See our User Agreement and Privacy Policy. One of the real benefits of this new model of software development is that it’s low friction: it’s easy to develop a library and make it available — you just write it put it up on a package repository like crates.io — and it’s easy to use those packages — you just add them to your build configuration. There are design questions about how exactly to express these kinds of bounds, which need to be addressed before stabilising complex const arguments. The index.json contains all the fully rendered text (as HTML!) We intend to lift these in future versions of Rust: see what's next. If you are a Rust project owner and are looking for contributors, please submit tasks here. These rules are already binding law, with the provisions for significant social media intermediaries coming into force 3 months from now (approximately late May 2021). If sites were delivered this way, there would be no caching, which As data, this is easily formatted as a pivot (ie, the If you have additional guidance on which versions of the OSes are affected, so that we can prevent Safari users from receiving broken images, it would be much appreciated! While technically speaking a hash function cannot be reversed, some web services have huge databases of pre-calculated MD5 hashes, so MD5 hashes of typical search queries can all be found there. Properly managing and nurturing an open source community is deeply complex work, involving a sustained amount of both attention and. In this graph from the nightly release of Firefox for Android two metrics started reporting a number of errors that’s far above any other error we see. “Not portable” generally means “LLVM does not support my retrocomputing hobby target.” This is mostly about dead ISAs like DEC Alpha. The post In March, we see Firefox 87 appeared first on Mozilla Hacks - the Web developer blog. that a client does not know that it needs yet. This feature automatically blocks third-party scripts, images, and other content from being loaded from cross-site tracking companies reported by Disconnect. Fortunately, we’re seeing a whole series of technological advancements that point the way to a solution without having to go back to the bad old days of writing everything yourself. Sync IPC markers are now available again unconditionally, New DoFlushPendingNotifications and SetNeedStyleFlush markers to make sync style flushes easy to understand, New Runnable markers to understand things using just a little bit of CPU on a thread (otherwise invisible in samples), Guanlin [:chenggu3] has been porting the DTD strings in videocontrols.js to Fluent (, Swapnik [:katkoor2] recently landed a fix where PiP would open a video with an invalid duration value via the keyboard shortcut (, Oliver [:popeoliv] has begun moving the PiP overrides embedded in the WebCompat add-on into its own system addon. I’m planning on holding two public drafting sessions tomorrow, March 23rd: During these sessions, we’ll be looking over the status quo issues If pushed resources are less important than resources the At this point, this pref should probably be removed, as we no longer need nor Please hop into a relevant Matrix room to chat: In a recent academic publication titled HTTPS-Only: Upgrading all connections to https in Web Browsers (to appear at MadWeb – Measurements, Attacks, and Defenses for the Web) we present a new browser connection model which paves the way to an ‘https-by-default’ web. The size is 145 mm x 30 mm x 30 mm. Together, we can make 2021 a great year for Firefox accessibility. Learn more about SmartBlock at Introducing SmartBlock. Milestone 7 targets Firefox 88. 365 pull requests were merged in the last week. In previous proposals, mappings were strictly one-to-one. Maybe providing a way to selectively request You could take all the very simple site like this, that allows all the code to be delivered in just FORMATIONS In building these extra-strong privacy protections in Private Browsing windows and Strict Mode, we have been confronted with a fundamental problem: introducing a policy that outright blocks trackers on the web inevitably risks blocking components that are essential for some websites to function properly. It is time we change our default Referrer Policy in line with these new goals. toward bundling[11]. The launcher process and the browser process share code that tracks whether Therefore, we need to be able to exercise some control over where Transparent community-based processes promote participation, accountability and trust. First a note: this is my personal opinion and an incomplete one at that. the --wait-for-browser command-line option. perspectives and experience. Each month I’ll highlight the regressions and improvements found. Our own "Papers and Research Projects" section needs filling! What we’re interested in is the general trend. fetches and cache optimization highlights – content from bundles need to be It still failed. The events of the last few years have demonstrated (conclusively, in my view) that open systems aren’t necessarily a protector against abuse by governments, technology monopolies and ill-intentioned groups of individuals alike. Quiet week, a couple regressions and several nice improvements. process. considerably faster on ad-heavy pages. Another issue with range-aware VM allocation is determining the location, within These vulnerabilities are very typical, I’ve seen similar mistakes in other extensions many times.
