How we’re building a browser when it’s supposed to be impossible (via) Andreas Kling: “The ECMAScript, HTML, and CSS specifications today are (for the most part) stellar technical documents whose algorithms can be implemented with considerably less effort and guesswork than in the past.” The Ladybird project is such an inspiration, and really demonstrates the enormous value of the work put in by web standards spec authors over the last twenty years. # 11th April 2023, 10:18 am
Web Stable Diffusion (via) I just ran the full Stable Diffusion image generation model entirely in my browser, and used it to generate an image (of two raccoons eating pie in the woods, see “via” link). I had to use Google Chrome Canary since this depends on WebGPU which still isn’t fully rolled out, but it worked perfectly. # 17th March 2023, 4:46 am
TabFS (via) “TabFS is a browser extension that mounts your browser tabs as a filesystem on your computer.” What a fascinating idea! Each browser tab gets a virtual directory (via FUSE) with “files” representing the tab title, contents and any resources that have been loaded by that page. You can edit files in those folders to live-update the content that’s loaded in your browser! # 19th February 2023, 4:08 pm
Servo to Advance in 2023 (via) This is excellent news: Serve, the browser-in-Rust project started by Mozilla in 2012 that produced the Rust programming language, is getting re-activated with four new full-time developers provided by Igalia.
Igalia are a fascinating organization—I hadn’t realized quite how influential they’ve been until I read their Wikipedia page just now
They’ve been around since 2001, and “in 2019 they were the #2 committers to both the WebKit and Chromium codebases and in the top 10 contributors to Gecko/Servo”—including implementing and maintaining CSS Grid Layout! # 16th January 2023, 5:08 pm
Ladybird: A new cross-platform browser project (via) Conventional wisdom is that building a new browser engine from scratch is impossible without enormous capital outlay and many people working together for many years. Andreas Kling has been disproving that for a while now with his SerenityOS from-scratch operating system project, which includes a brand new browser implemented in C++. Now Andreas is announcing his plans to extract that browser as Ladybird and make it run across multiple platforms. Andreas is a former WebKit engineer (at Nokia and then Apple) and really knows his stuff: Ladybird already passes the Acid3 test! # 12th September 2022, 7:34 pm
I’m not convinced that reusing X-Frame-Options: DENY would be the best approach—I think it would break too many existing legitimate uses—but a similar option (or a similar header) specifically for native apps which causes pages to load in the native OS browser instead sounds like a fantastic idea to me. # 10th August 2022, 10:29 pm
Paint Holding—reducing the flash of white on same-origin navigations. I missed this when it happened back in 2019: Chrome (and apparently Safari too—not sure about Firefox) implemented a feature where rather than showing a blank screen in between page navigations Chrome “waits briefly before starting to paint, especially if the page is fast enough”. As a result, fast loading multi-page applications become almost indistinguishable from SPAs (single-page apps). It’s a really neat feature, and now that I know how it works I realize that it explains why page navigations have felt a lot snappier to me over the past few years. # 22nd May 2022, 2:50 am
servefolder.dev (via) Absurdly clever application of service workers and the file system API: you can select a folder from your computer and the contents of that folder will be served (just to you) from a path on this website—all without uploading any content. The code is on GitHub and offers a useful, succinct introduction to how to use those APIs. # 12th December 2021, 6:32 pm
Beginning in M94, Chrome will offer HTTPS-First Mode, which will attempt to upgrade all page loads to HTTPS and display a full-page warning before loading sites that don’t support it. Users who enable this mode gain confidence that Chrome is connecting them to sites over HTTPS whenever possible, and that they will see a warning before connecting to sites over HTTP. Based on ecosystem feedback, we’ll explore making HTTPS-First mode the default for all users in the future.

Google is not trying to break the web by pushing for more HTTPS. Neither is Mozilla and neither are any of the other orgs saying “Hey, it would be good if traffic wasn’t eavesdropped on or modified”. This is fixing a deficiency in the web as it has stood for years.

Could browsers be made to scroll down (e.g. by 67%) if you add #67% to a URL?
I’d say no.[... 89 words]
What is a Polyfill? Useful new term: a Polyfill is “a shim that mimics a future API providing fallback functionality to older browsers”. # 9th October 2010, 11:48 am
Velocity: Forcing Gzip Compression. Almost every browser supports gzip these days, but 15% of web requests have had their Accept-Encoding header stripped or mangled, generally due to poorly implemented proxies or anti-virus software. Steve Souders passes on a trick used by Google Search, where an iframe is used to test the browser’s gzip support and set a cookie to force gzipping of future pages. # 30th September 2010, 5:45 pm
WebKit, Mobile, and Progress. Alex Russell responds to PPK’s analysis of the many different WebKit variants in today’s mobile phones, pointing out that the replacement cycle and increasing quality of WebKit in more recent phones means the situation still looks pretty good. # 10th October 2009, 12:28 am
CSS 3: Progress! Alex Russell on the new exciting stuff going in to CSS 3 based on real-world implementations in the modern set of browsers. Of particular interest is the new Flexible Box specification, which specifies new layout primitives hbox and vbox (as seen in XUL) and is already supported by both WebKit and Gecko. # 22nd August 2009, 11:52 am
Microsoft backs long life for IE6. Oh FFS... “The software giant said it would support IE6 until 2014—four years beyond the original deadline.” # 14th August 2009, 2:53 pm
MoD sticks with insecure browser. Tom Watson MP used parliamentary written answers to find out that the majority of government departments still require their staff to use IE6, and not all of them have upgrade plans to 7 or 8. Not a single department considered an alternative browser. “Many civil servants use web browsers as a tool of their trade. They’re as important as pens and paper. So to force them to use the most decrepit browser in the world is a rare form of workplace cruelty that should be stopped.” # 24th July 2009, 10:18 am
HTML 5 Parsing. Firefox nightlies include a new parser that implements the HTML5 parsing algorithm (disabled by default), which uses C++ code automatically generated from Henri Sivonen’s Java parser first used in the HTML5 validator. # 11th July 2009, 11:36 pm
Firefox 3.5 for developers. It’s out today, and the feature list is huge. Highlights include HTML 5 drag ’n’ drop, audio and video elements, offline resources, downloadable fonts, text-shadow, CSS transforms with -moz-transform, localStorage, geolocation, web workers, trackpad swipe events, native JSON, cross-site HTTP requests, text API for canvas, defer attribute for the script element and TraceMonkey for better JS performance! # 30th June 2009, 6:08 pm
Google asked people in Times Square:“What is a browser?”. Stuff like this makes me despair for creating a secure web—what chance do people have of surfing safely if they don’t understand browsers, web sites, operating systems, DNS, URLs, SSL, certificates... # 20th June 2009, 1:25 am
Changes in Opera’s user agent string format (via) How depressing... Opera 10 will ship with 9.80 in the User-Agent string because badly written browser sniffing scripts can’t cope with double digits. # 28th May 2009, 1:16 am
Critical Mac OS X Java Vulnerabilities. There’s a five month old Java arbitrary code execution vulnerability which hasn’t yet been patched by Apple. Disable Java applets in your browser until it’s fixed, or random web pages could execute commands on your machine as your user account. # 19th May 2009, 7:07 pm
Cross Browser Base64 Encoded Images Embedded in HTML (via) Scarily clever. View the PHP source to see what’s going on—most browsers get image tags that use data URIs starting with data:image/png;base64, but IE gets served a Content-type:message/rfc822 header and a MIME formatted multipart/related document, as used by e-mail clients to embed inline image attachments. # 17th April 2009, 4:12 pm
10 Cool Things We’ll Be Able To Do Once IE6 Is Dead. Highlights include child and attribute selectors, 24bit PNGs and max-width and min-width. Simple pleasures, but I can hardly wait. # 15th April 2009, 2:17 pm
Pwn2Own trifecta: Hacker exploits IE8, Firefox, Safari. You just can’t trust browser security: Current versions of Safari, IE8 and Firefox all fell to zero-day flaws at an exploit competition. None of the vulnerabilities have been disclosed yet. # 19th March 2009, 3:30 pm
CSRF is not a security issue for the Web. A well-designed Web service should be capable of receiving requests directed by any host, by design, with appropriate authentication where needed. If browsers create a security issue because they allow scripts to automatically direct requests with stored security credentials onto third-party sites, without any user intervention/configuration, then the obvious fix is within the browser.
