Developer of sorts at Firefox. No thought goes unpublished. He/him.

Oh hello! We've had a bit of a rename & rebrand (formally FirefoxDevTools), but the content will be roughly the same as it's been for the past few months.

We're looking forward to posting more on web platform & DevTools features.

I'm playing around with JPEG XL's "JPEG repackaging" feature. It repackaged a 147kb JPEG down to 126kb, but on my Pixel 10, the new file takes 78ms to decode, vs 10ms for the JPEG.

At 3g+ speeds… that feels like a performance loss.

Another API proposal from TPAC: CSS routes and navigation queries, meaning less JavaScript is needed for view transitions!

We have Custom Elements, but do we also need Custom Attributes?

This was discussed at TPAC. Is it something you'd like on the platform?

Cheers folks! I'll go for a much more subtle version of that effect. Hopefully that'll work for most people.
How do you feel about the word-by-word highlighting?

I used https://github.com/m-bain/whisperX for local transcription & word by word timestamps. This was much more accurate than the results directly from OpenAI.

A lot of you asked for burned-in subtitles. I agree, it was already on my todo list, and well, I had a long flight, so it was something to do.

I'll improve the segmenting for the next real video, but so far so good.

Out-of-order HTML patching, another proposal from TPAC, lets HTML be presented non-linearly, and a single file can update multiple parts of the page.

Would this feature be useful to you?

Uploading video is super unreliable on mastodon huh
