Last Updated: June 3, 2022. The intent of this post is to capture a list of non-obvious features of the browser that might be useful to you. Q: How do I find the tab playing audio? It’s cool that Microsoft Edge shows the volume icon in the tab playing music and I can click toContinue reading “Microsoft Edge Tips and Tricks”
Leading and trailing whitespace are generally invisible. Humans are bad at dealing with things they can’t see. If your system accepts textual codes, or any other human-generated or human-mediated input, you should trim whitespace, whether it’s leading, trailing, or inline (if not meaningful). // Trim leading and trailing whitespace $(‘inputCode’).value = $(‘inputCode’).value.trim(); It’s downright sillyContinue reading “Trim Your Whitespace”
Curious about how to see a website’s HTTPS certificate in Microsoft Edge? You’ve got two options: A companion post to 2017’s post Inspecting Certificates in Chrome.
Last year, I wrote about how the new Microsoft Edge browser mostly ignores Security Zones (except in very rare circumstances) to configure security and permissions decisions. Instead, in Chromium per-site permissions are controlled by settings and policies expressed using a simple syntax with limited wildcarding support. Settings Page’s Site Permissions and Group Policy Internet ExplorerContinue reading “Per-Site Permissions in Edge”
One of my final projects on the Chrome team was writing an internal document outlining Best Practices for Secure URL Display. Yesterday, it got checked into the public Chromium repro, so if this is a topic that interests you, please have a look! Additionally, at Enigma 2019, the Chrome team released Trickuri (pronounced “trickery”) a tool forContinue reading “Securely Displaying URLs”
Chrome 60 introduces a new option to quickly show Certificate information for the current page.
“Magic” is great… except when it isn’t. Software Design is largely about tradeoffs, and one of the more interesting tradeoffs is between user experience and predictability. This has come up repeatedly throughout my career and in two independent contexts yesterday that I’ll describe in this post. Developer Magic I’m working on a tiny UX changeContinue reading “The Trouble with Magic”
One unfortunate (albeit entirely predictable) consequence of making HTTPS certificates “fast, open, automated, and free” is that both good guys and bad guys alike will take advantage of the offer and obtain HTTPS certificates for their websites. Today’s bad guys can easily turn a run-of-the-mill phishing spoof: …into a somewhat more convincing version, by obtainingContinue reading “Certified Malice”
When building applications that display untrusted content, security designers have a major problem— if an attacker has full control of a block of pixels, he can make those pixels look like anything he wants, including the UI of the application itself. He can then induce the user to undertake an unsafe action, and a userContinue reading “The Line of Death”
The combined address box and search bar at the top of the Chrome window is called the omnibox. The icon and optional verbose state text adjacent to that icon are collectively known as the Security Chip: The security chip can render in a number of states, depending on the status of the page: Secure –Continue reading “Security UI in Chrome”
