Shades of the first browser wars. This is sometimes the right thing but too much and we get tower-of-Babel confusion and extensions that don't go away.
We're not extending SpiderMonkey in Firefox with things not proposed or already in the harmony: namespace. We are also not yet agreed on shipping Proxy in Firefox 4. It's easy to slap on a vendor prefix, but hard to take that away later, and it degrades usability testing subtly. /be On Jul 2, 2010, at 10:24 AM, Erik Arvidsson wrote: > FYI > > Both Mozilla and WebKit have vendor prefixes in DOM extensions. > > window.webkitNotifications > window.mozPaintCount > > > > Chrome added some as well but we use a single object. > > > > chrome.csi(); > chrome.loadTimes() > > On Fri, Jul 2, 2010 at 09:23, Allen Wirfs-Brock > <allen.wirfs-br...@microsoft.com> wrote: > I just noticed from John Resig’s Twitter stream that Proxies are now in the > FF nightlies.
