@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).

@gundersen would you be ok if it was behind a site permission addon? https://support.mozilla.org/en-US/kb/site-permission-add-ons

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

@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.

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

This (and for the style selection ui to be more visible again): https://bugzilla.mozilla.org/show_bug.cgi?id=216537 -

@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.
