In 2005, one of my first projects on the Internet Explorer team was improving the user-experience for HTTPS sites (“SSLUX”). Our first task was to change the certificate error experience from the confusing and misleading modal dialog box: … to something that more clearly conveyed the risk and which more clearly discouraged users from acceptingContinue reading “Extended Validation Certificates – The Introduction”

Automatically Evaluating Compressibility
Fiddler’s Transformer tab has long been a simple way to examine the use of HTTP compression of web assets, especially as new compression engines (like Zopfli) and compression formats (like Brotli) arose. However, the one-Session-at-a-time design of the Transformer tab means it is cumbersome to use to evaluate the compressibility of an entire page orContinue reading “Automatically Evaluating Compressibility”
Putting Users First
When I worked on Internet Explorer, the team was proud of the fact that we could claim to be more aligned with our users’ goals than either of our major competitors (both of whom were funded almost entirely by advertising). IE, the story went, was paid for by users who purchased Windows, and thus ourContinue reading “Putting Users First”
My Next Adventure
Back in 2004, I couldn’t get the tiny IE team interested in fixing caching bugs that were causing my team’s website to break in bizarre and unpredictable ways. I figured I’d hop over there, fix some bugs, and move along. I quickly realized that I was hopelessly in love with browsers in general and securityContinue reading “My Next Adventure”
The Sad State of HAR
Spring 2017 Update: Some of these issues have been fixed. The HTTP Archive Format (HAR) was designed to allow tools to exchange network traffic using a standard format; this format is akin to Fiddler’s Session Archive Zip format but is supported natively by browser developer tools. Unlike SAZ files, it is not compressed by default,Continue reading “The Sad State of HAR”
Duct Tape and Baling Wire–Cookie Prefixes
Update: Cookie Prefixes are supported by Chrome 49, Opera 36, and Firefox 50. Test page; no status from the Edge team. A new cookie feature called SameSite Cookies has been shipped by Chrome, Firefox and Edge; it addresses slightly different threats. When I worked on Internet Explorer, we were severely constrained on development resources. WhileContinue reading “Duct Tape and Baling Wire–Cookie Prefixes”
Help–The Whole Web Thinks I’m Using IE7!!!
Every few weeks for the last six or so years, I see someone complain on Twitter or in forums that the entire Internet seems to think they’re running an old version of IE. For instance, an IE11 user on Windows 8.1 might see the following warning on Facebook: These warnings typically occur when the browserContinue reading “Help–The Whole Web Thinks I’m Using IE7!!!”
Developer Advocacy
The Microsoft Edge (nee Internet Explorer) team held one of their “#AskMSEdge chats” on Twitter yesterday. After watching the stream, @MarkXA neatly summarized the chat: The folks over on WindowsCentral built out a larger summary of the tidbits of news that did get answered on the chat, some of which were just pointers to theirContinue reading “Developer Advocacy”
Brotli
2022 Update: Brotli is requested by 94% of browsers, offers great performance, and works amazingly well on Web Assembly code. If you’re still using GZIP today, you should update! Regular readers of my blog know how much I love Zopfli, Google’s compression engine that often shrinks output by 5% or better when compared to theContinue reading “Brotli”
On Defaults
Yesterday, Chris Beard, the CEO of Mozilla, wrote an open letter to Microsoft complaining about Windows 10’s behavior related to default applications. Reactions were all over the board, but in my Twitter feed, at least, they mostly skewed against Mozilla. With the perspective of having been both inside and outside Microsoft, I feel compelled toContinue reading “On Defaults”
