If you had to pick _one_, which web platform feature would you like in Firefox that isn't part of the Interop 2026 effort?

@firefoxwebdevs XSLT. Keep 1.0 support and add in support for 2.0 and 3.0
@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.

@Lukew @firefoxwebdevs Most of the time, I've seen drop-down, but any of them can be a very good start

@Thain @firefoxwebdevs fwiw Chrome 145 has listbox multiple and it's in the spec too! So hopefully Firefox and WebKit can do this alongside the dropdown single select version (though it's quite a large undertaking overall due to history)

@Thain @firefoxwebdevs nice thing with this is that you can build a custom dropdown multiselect yourself. It'll need JS and the accessibility handling correctly but it's doable now, without you needing to recreate the listbox itself. I suspect that's what most people will end up doing anyway for full control of the design. e.g. an input in the picker for filtering.

@Lukew @firefoxwebdevs The reason I want it is for the accessibiliy. Most of the time (always?); the input + dropdown are inaccessible.

@Thain @firefoxwebdevs yeah `<select multiple size=1>` is still being worked on, but hopefully soon. Then even stuff like filtering is still being thought about. Hopefully without any JS we can manage the common scenarios.

@bundyo ohhh, what's in V2 that you particularly want?

To work with elements in transformed containers, at least. And anchored containers as a wish.

@firefoxwebdevs Speculation Rules API
-
@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.
@ArneBab
Instead of doing that, I like the technique of making the input `opacity: 0` and positioning it over the label. If you put the input inside the label, you can use `:focus-within` to show focus.https://www.sarasoueidan.com/blog/inclusively-hiding-and-styling-checkboxes-and-radio-buttons/

@firefoxwebdevs File System Access API. I'd be fine if you carved out `showDirectoryPicker()`, or put it behind a scary permission prompt. It enables so many powerful editor-like apps, from Photoshop to VS Code.
