The name of these diagrams gives me equal parts pride and embarrassment.

We're experimenting with a way to visualize session history in Firefox DevTools, and we'd love your feedback!

Here's the background, and how to try it: https://blog.farre.se/posts/2026/06/01/session-history-diagrams/

Spent years chasing session history bugs by squinting at logs. Finally built the thing that draws it instead, a Firefox DevTools panel with live Jake diagrams, nested iframes and all. Behind a pref in Nightly.

Session History Diagrams in Firefox DevTools

I’ve spent a lot of time at Mozilla working on session history, the machinery that keeps track of where you’ve been so the back and forward buttons do something sensible. It’s one of those parts of the browser that sounds simple from the outside and turns out to be anything but. Once you add iframes, nested iframes, and the subtle rules about when a navigation creates a new entry versus replacing the current one, the state you’re reasoning about gets large and hard to hold in your head.

Just thinking back to all the times I've helped junior colleagues grow into better engineers and leaders by reminding them 60 times a day to not hallucinate.

Just published a Firefox extension to add a little feature I wanted: "Open Link in Unloaded Tab". https://addons.mozilla.org/en-US/firefox/addon/open-link-in-unloaded-tab/

Open Link in Unloaded Tab – Get this Extension for 🦊 Firefox (en-US)

Download Open Link in Unloaded Tab for Firefox. Adds "Open Link in Unloaded Tab" to the context menu.

Dear Lazyweb, I'm looking to buy a refurbed laptop. I want something with a fairly slim and nice form factor, ~14". It needs to be able to handle compiling fairly well, be able to run rr, good Linux compatibility, have an open memory slot. Non-programming use would stop at Netflix and Phoenix Point.

I'm thinking Lenovo T14 G2 AMD Ryzen 7 Pro, but I can't find anyone selling it (where shipping isn't doubling the price), so alternatives would be highly appreciated.

Escape From New York (1981). Holy hell, this is a good one. Everybody's in it. Russel, Van Cleef, Barbeau, Stanton, Atkins, etc. And the music. The music and the visuals. Just saw it on a big screen, and I'm a bit blown away.
