[1/3] Today marks my last day at Google & in Germany. I’m heading back to Malaysia! 🇲🇾 It’s been an incredible 5 years working on #ChromeDevTools and browser automation with the best team ever – the amazing Chrome team! 💙 One of the promises I made to myself when joining was to bring...
Discovery of the day: devtools logpoints. Instead of adding console.log directly in the code, you can add a logpoint in devtools (at least in Chrome). The brilliant @jec.fish has a video about this: youtu.be/JyHjoaUhAus. No more forgotten log lines! 🙌🏻
Uh oh, glitches? 😬 Our latest What's New in #ChromeDevTools has the answers (and more!). Watch the full update here: lnkd.in/gT9pWkha @matthiasrohmer.bsky.social

If you're using Speculation Rules there's a small bug in Chrome 133 (just rolling out now) where DevTools + Local Overrides causes prerenders to crash 😢 This only happens with DevTools open and when Local Overrides are enabled so shouldn't affect most of your users—but annoying for us developers!
