announcement by Elliot Glaysher at https://groups.google.com/a/chromium.org/forum/#!topic/chromium-dev/Zpu9801pPRc. Quote:

Google Chrome to Kill Plugin
netscape back in 1990s created a plugin API architecture, called NPAPI. That's what allows you to have (Macromedia) Flash, Apple's QuickTime (for video), display MathML, use Java applets, and hundreds of others. Now, Google is killing it, and pulling it out of Google Chrome.
This means, no more Java Applets. By the way, the Flash bundled with Google Chrome isn't using NPAPI.
Google cites security reasons for killing NPAPI.

Do Not Use Dart or CoffeeScript
Do not use Dart or CoffeeScript. Just use plain JavaScript. If you must use something fancy, use TypeScript.
Dart is basically JavaScript with Java syntax ＆ semantics. Java is bad. Goole do it because Google can't divorce Java.
CoffeeScript is no good because it's a layer of complexity, with ad-hoc syntax, and benefit isn't big enough. It will never be standard.
TypeScript is acceptable, because it's JavaScript compatible, with benefit of type system (math foundation❕)，not hacker whims of idioms ＆ styles ＆ patterns ＆ OOP crud.

browser extension development explained: Google vs Firefox
for Google Chrome, you go to their tutorial, in 20 min, you know how to write one, how to pack it, and have a good overview of the API. Pure JavaScript HTML CSS.
for Firefox, there are meta-guide old and new on mozilla blogs, then there are 3 frameworks, one requires to download a SDK that runs python that it asks you to run its random bin/activate fk bash script with instruction about how to untar a tarball, and one is “bootstrap” fk, and another is XUL fk, each fk has their own introduction page, with one thousand links ＆ jargons ＆ guides ＆ warnings ＆ preface ＆ idioms guides. In 1 hour, u still dunno a thing about it.
randomize a html list
took me 3 hours to write a trivial 15 lines JavaScript code to randomize a list. See result here. Vocabulary: Words in Olympia Reader (view source to see the code)
i blame the besotted nature of the DOOM. NodeList, HTMLCollection, live vs not live, readable vs not readable, whitespace nodes, … truely hell.
but no, i did not subjugate myself to the lure of jQuery.
