And of course its half-done. Asks me if I want the site to allow use of my non existing camera, and the options dropdown just has a (none) entry in it.

It's the same approach as with downloads. To this day, the only browser to support resuming downloads (and making use of HTTP range) is Opera.

Opera is not the only browser to support resuming downloads. With the appropriate server headers and local state, Safari and FireFox can also resume downloads.

I believe Chrome does as well.

As a developer I like that I can use the API now instead of just reading about it. Chrome rolls out updates very smoothly and rapidly, who cares if the initial support of a very new standard is not perfect? It sure beats the support that FireFox, IE and Safari have (none).

For this particular feature; there are plenty that Chrome doesn't support fully (IndexedDB) or at all (CSS calc) that those other browsers have had for quite a long time.

Do you mean this IndexedDB? http://caniuse.com/#feat=indexeddb . Or this calc? http://caniuse.com/#feat=calc . They look pretty supported to me, remembering that they're both based on a draft specs.

Calc must be new; this is great, this means Firefox, WebKit, and IE10 all have it.

IndexedDB is using an outdated spec more than 8 months old.

Have you actually tried to use IndexedDB in Chrome? It's on an outdated spec draft from around a year ago.

CSS calc has been in Chrome (behind a -webkit prefix) since Chrome 19.

Firefox got support for getUserMedia in July... https://hacks.mozilla.org/2012/07/getusermedia-is-ready-to-r...

Using Nightly go to about:config and enable the media.navigator.enabled pref, then you can test it out at this page: https://people.mozilla.com/~anarayanan/gum_test.html

That's not support. Support is on the shipping main branch. Chrome has had support for a while too if you wanted to jump through some hoops.

Why is that half-done? What should it have done instead?

Maybe you have some USB camera you want to plug in when some site makes such request.

Tell me I don't have a webcam connected and inform me that this site requires one, and possibly wait for me to connect one.

Right now, I get the permission bar, click "accept" and it fails silently. And the "none" thing is really just a bad taste; you don't offer UI elements when they don't do anything.

(I didn't try, but I think that permission dialog wouldn't even recognize it when I connected a camera after it opened)

I don't agree, as others have said, this dialog could have served to remind you that you had forgotten to plug in your USB webcam.

These days, no camera is surely an edge case that I think they handled fine.
