Earlier quoted context omitted.
Are you trolling? The three highlighted features are 'new addons manager,' webm support, and fixing the :visited privacy issue. NONE of these are in any released Chrome, although the early early preview of Chrome 6 has WebM support. Of the three UI elements highlighted, tabs on top is the only one in Chrome (or did I miss the Chrome button in some developer preview?).
From my view, the highest highlighted feature was the tabs, followed by the 3 you mention. I counted WebM as Chrome, given that it is Google's codec, but I'm not sure its in Chrome 5 either :(. Looking further down, I was thinking that WebSockets, Indexed DB, Crash Protection, and the key feature of JetPack (Add-Ons not requiring restart) were all pioneered by Chrome. That leaves The Web Console, which I have not yet…
According to wikipedia, Chrome 5 does not support WebM: http://en.wikipedia.org/wiki/Chrome_%28browser%29
WebSockets: Yay, you're finally right, Chrome did pioneer WebSockets. Sadly, it did not update its implementation to reflect the changes to the standard based on feedback from the numerous other browser vendors that actually implemented it but chose not to release it because of it volatility.
IndexedDB: Google was actually pushing for Web SQL Database, which got rejected. Learn more here: http://hacks.mozilla.org/2010/06/beyond-html5-database-apis-...
Crash Protection: IE8 was the first browser with this feature.
Jetpack: Ok, this one is important right? So for bonus points, let's look at the first jetpack release: https://addons.mozilla.org/en-US/firefox/addon/12025/version... (scroll the to bottom: May 20, 2009)
Now for Google's launch of their great extensions platform: http://techcrunch.com/2009/12/08/chrome-extensions-live/ (December 08, 2009). Darn, guess Google stole that one from Mozilla's playbook (and yet, still no powerful extensions :().
WebConsole: Everyone and their mom has been using Firebug since the dawn of time. Chrome wasn't even an inkling in Google's eye then.
HTML5: Firefox 4 is STILL the only browser to support HTML 5 parsing. Previous versions of course supported other features such as video and audio, but since you didn't go into details here, I'll leave it at that.
CSS3: No details again? Ok, well rounded corners has been in Firefox so long I can't even remember (1.5 or 2?). Lots of these features were around before Chrome existed. But no more for this since you only mentioned it in passing.
Call me a fool for taking the bait (http://xkcd.com/386/), but with all due respect please stop trolling, and learn about what you're talking about before you speak.
