Option 1: Command-line download extension as zip and extract

extension_id=jifpbeccnghkjeaalbbjmodiffmgedin   # change this ID
curl -L -o "$extension_id.zip" "https://clients2.google.com/service/update2/crx?response=redirect&os=mac&arch=x86-64&nacl_arch=x86-64&prod=chromecrx&prodchannel=stable&prodversion=44.0.2403.130&x=id%3D$extension_id%26uc" 
unzip -d "$extension_id-source" "$extension_id.zip"

Thx to crxviewer for the magic download URL.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

As a maintainer of native node add-on modules I have some questions about when and why NODE_MODULE_VERSION changes:

(@rvagg has anwered these in the comments below)

does v8 use semver? how do you know when a v8 version breaks ABI compatibilility?
is there a semantic meaning for v8 version numbers or is it arbitrary?
who maintains this google doc I found? is it official?
why is the latest entry from may in the v8 changelog? https://chromium.googlesource.com/v8/v8.git/+/master/ChangeLog
how can you tell when all these future v8 versions will be stable? https://chromium.googlesource.com/v8/v8.git/+refs
why must a node major version correspond to a specific v8 version? e.g. node v5 uses v8 4.6 and won't upgrade to 4.7

DEPRECATED

I think most of this stuff is now depracted. Looks like C++ is the only realistic way to go for implementing WebIDL bindings in Gecko. That's unfortuante, because if you are a JS dev, learning C++ can be challenging (though worth while! it's a fun language.)

Implementing a JS-based WebIDL binding in Gecko

This provides a gentle introduction to implementing a WebIDL interface in JavaScript. Once you are done, you can refer to the MDN Wiki, to add more advanced things.

Before you start

We would encourage you to first build a simple prototype version of your API in JS. Going through the process of creating a WebIDL is fairly straight forward, but if you screw it up you will need to recreate a whole bunch of files, etc. As such, it's much easier to make sure you have your API in a good state before attempting the steps below.
