@firefoxwebdevs Customizable Selects would be great.

@ArneBab that's part of Interop 2026! So you get another pick for free
@firefoxwebdevs ah, I misunderstood
- when I have a label with tabindex=0 for a radio-button that’s display=none, I can click the label to toggle the radio-button and I can tab into it, but I cannot toggle the radio-button by clicking enter or space after tabbing into it.
Otherwise I’m actually pretty happy.
-
@firefoxwebdevs Customizable selects would be great of course, but it’s maybe a bit too early. This is a feature that shouldn’t be rushed.
@mvsde I wanted to ask for these, too, but agree that they need to be done well.
Recently used select2 and the amount of CSS hacks needed to make it behave as I needed and to make it accessible was far too big.

@firefoxwebdevs web serial api!!!!

@firefoxwebdevs Customizable Selects would be great.
@herschel_r we're actively working on it

@mvsde it's definitely not too early, we're actively working on it

@firefoxwebdevs selfishly as I want it on my blog, initial-letter support.

@firefoxwebdevs I would've liked to see mobile testing being more reliable and forming part of the main dashboard. It's such a big area to still not be included. I'm aware it's in under investigation, but it's there for a few years now.
If I had to pick one, probably WebNotifications. I use them a lot as a user and there's loads of differences between browsers. None of them work perfectly, but Firefox and Safari in particular are missing a lot of important features like image, renotify, silent and icon (Safari iOS).

@firefoxwebdevs my faves are in Interop 2026. It is an exciting set!
If I had to add one for Firefox it would be progress() https://webstatus.dev/features/progress-function

@job I can't imagine newer versions of XSLT being added. I don't think you'll be happy with this, but you can transform XML with JS https://jakearchibald.com/2025/making-xml-human-readable-without-xslt/

@firefoxwebdevs the CloseWatcher API (I guess maybe implicitly we get that from closedby?).
field-sizing: content would be a nice win too.

Directly support Anchor Positioning API v2
It will nicely supplement the dialog APIs too.
